For Moses describeth the righteousness which is of the law, That the man which doeth those things shall live by them. But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:) Or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.) But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; [Deuteronomy 30:12-14] That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. For the scripture saith, Whosoever believeth on him shall not be ashamed. For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. For whosoever shall call upon the name of the Lord shall be saved.
Deuteronomy 30
1 And it shall come to pass, when all these things are come upon thee, the blessing and the curse, which I have set before thee, and thou shalt call them to mind among all the nations, whither the LORD thy God hath driven thee, 2 And shalt return unto the LORD thy God, and shalt obey his voice according to all that I command thee this day, thou and thy children, with all thine heart, and with all thy soul; 3 That then the LORD thy God will turn thy captivity, and have compassion upon thee, and will return and gather thee from all the nations, whither the LORD thy God hath scattered thee. 4 If any of thine be driven out unto the outmost parts of heaven, from thence will the LORD thy God gather thee, and from thence will he fetch thee: 5 And the LORD thy God will bring thee into the land which thy fathers possessed, and thou shalt possess it; and he will do thee good, and multiply thee above thy fathers. 6 And the LORD thy God will circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live. 7 And the LORD thy God will put all these curses upon thine enemies, and on them that hate thee, which persecuted thee. 8 And thou shalt return and obey the voice of the LORD, and do all his commandments which I command thee this day. 9 And the LORD thy God will make thee plenteous in every work of thine hand, in the fruit of thy body, and in the fruit of thy cattle, and in the fruit of thy land, for good: for the LORD will again rejoice over thee for good, as he rejoiced over thy fathers: 10 If thou shalt hearken unto the voice of the LORD thy God, to keep his commandments and his statutes which are written in this book of the law, and if thou turn unto the LORD thy God with all thine heart, and with all thy soul. 11 For this commandment which I command thee this day, it is not hidden from thee, neither is it far off. 12 It is not in heaven, that thou shouldest say, Who shall go up for us to heaven, and bring it unto us, that we may hear it, and do it? 13 Neither is it beyond the sea, that thou shouldest say, Who shall go over the sea for us, and bring it unto us, that we may hear it, and do it? 14 But the word is very nigh unto thee, in thy mouth, and in thy heart, that thou mayest do it. 15 See, I have set before thee this day life and good, and death and evil; 16 In that I command thee this day to love the LORD thy God, to walk in his ways, and to keep his commandments and his statutes and his judgments, that thou mayest live and multiply: and the LORD thy God shall bless thee in the land whither thou goest to possess it. 17 But if thine heart turn away, so that thou wilt not hear, but shalt be drawn away, and worship other gods, and serve them; 18 I denounce unto you this day, that ye shall surely perish, and that ye shall not prolong your days upon the land, whither thou passest over Jordan to go to possess it. 19 I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live: 20 That thou mayest love the LORD thy God, and that thou mayest obey his voice, and that thou mayest cleave unto him: for he is thy life, and the length of thy days: that thou mayest dwell in the land which the LORD sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.
Commentaries
But when the Pharisees had heard that he had put the Sadducees to silence, they were gathered together. Then one of them, which was a lawyer, asked him a question, tempting him, and saying, Master, which is the great commandment in the law? Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. [Deuteronomy 30:6] This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets.
And one of the scribes came, and having heard them reasoning together, and perceiving that he had answered them well, asked him, Which is the first commandment of all? And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment. [Deuteronomy 30:6] And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these. And the scribe said unto him, Well, Master, thou hast said the truth: for there is one God; and there is none other but he: And to love him with all the heart, and with all the understanding, and with all the soul, and with all the strength, and to love his neighbour as himself, is more than all whole burnt offerings and sacrifices. And when Jesus saw that he answered discreetly, he said unto him, Thou art not far from the kingdom of God. And no man after that durst ask him any question.
And, behold, a certain lawyer stood up, and tempted him, saying, Master, what shall I do to inherit eternal life? He said unto him, What is written in the law? how readest thou? And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself. [Deuteronomy 30:6] And he said unto him, Thou hast answered right: this do, and thou shalt live. But he, willing to justify himself, said unto Jesus, And who is my neighbour? And Jesus answering said, A certain man went down from Jerusalem to Jericho, and fell among thieves, which stripped him of his raiment, and wounded him, and departed, leaving him half dead. And by chance there came down a certain priest that way: and when he saw him, he passed by on the other side. And likewise a Levite, when he was at the place, came and looked on him, and passed by on the other side. But a certain Samaritan, as he journeyed, came where he was: and when he saw him, he had compassion on him, And went to him, and bound up his wounds, pouring in oil and wine, and set him on his own beast, and brought him to an inn, and took care of him. And on the morrow when he departed, he took out two pence, and gave them to the host, and said unto him, Take care of him; and whatsoever thou spendest more, when I come again, I will repay thee. Which now of these three, thinkest thou, was neighbour unto him that fell among the thieves? And he said, He that showed mercy on him. Then said Jesus unto him, Go, and do thou likewise.
"Anyone who tries to act high-handedly annoys God," says Scripture. For bombast is a spiritual vice. Scripture tells us to repent from it as from the other vices by turning from disharmony and by linking ourselves to a change for the better through the three instruments of mouth, heart and hands.

But consider if perhaps all people participate in him insofar as he is Word. This is why the apostle teaches us that he is sought within the seekers by those who choose to find him. He says, "Do not say in your heart, 'Who shall ascend into heaven?' that is, to bring Christ down; or, 'Who shall descend into the deep?' that is, to bring Christ up again from the dead. But what does the Scripture say? The Word is near you, even in your mouth, and in your heart." This is as though Christ and the Word which is sought are the same.
But what does Scripture say? The Word is very near you, in your mouth and in your heart. And to these the Savior also kindly points out the matters pertaining to the kingdom of God, that they may not seek it outside themselves or say, "Behold here or behold there." For he says to them, "The kingdom of God is within you."
The "kingdom of God," according to the word of our Lord and Savior, "comes not with observation"; and "neither shall they say: Behold here, or behold there"—but "the kingdom of God is within us" (for "the Word is very nigh unto" us, "in our mouth and in our heart"). So it is clear that he who prays for the coming of the kingdom of God rightly prays that the kingdom of God might be established and bear fruit and be perfected in himself.

There is a certain balance constructed in the interior of each of us by our Creator, on which it is possible to judge the nature of things. "I have set before you life and death, good and evil," two natures contrary to each other. Balance them against each other in your own tribunal.
Source: HOMILY ON PSALM 61:4
Let us ponder the nature of life and of death. Life is the enjoyment of the gift of breath, death the deprivation of it. Further, this gift of breath is considered by most people as a good. And so life is this, the enjoyment of goods, but death is the divestiture of them. And Scripture says, "Behold, I have set before your face life and death, good and evil," for it calls life good and death evil and attributes to each its proper deserts.
Source: DEATH AS A GOOD 1.2
For since, as it is written, man is confronted equally with life and death and stretches out his hand toward what he wants, it is necessary that whatever a man grasps with his hands in time he must possess forever in eternity. What here he cleaves to in affection, he must in the future cleave to forever, with his will and mind wholly fixed upon it.
Source: FOUR BOOKS OF TIMOTHY TO THE CHURCH 1.1.7
As he himself said … "Behold before you are fire and water, death and life. Choose life, that you may live." Everything we mentioned above, that is, good and evil, is contained in these two. For heaven and hell, Christ and the devil, height and depth are proposed to us in them. Through his grace God has put it into the power of each one to choose and to stretch out his hand to whatever he wishes.
Source: SERMON 149.1
Behold, man, you have before you "water and fire, life and death, good and evil," heaven and hell, the legitimate king and a cruel tyrant, the false sweetness of the world and the true blessedness of paradise. Power is given to you through the grace of Christ: "Stretch forth your hand to whichever you choose." "Choose life, that you may live"; leave the broad way on the left which drags you to death and cling to the narrow path on the right which happily leads you to life. Do not allow the wideness of that road on the left to keep you or give you pleasure.

You may say it is very different for God because He could, if He pleased, alter people's characters, and we can't. But this difference doesn't go quite as deep as we may at first think. God has made it a rule for Himself that He won't alter people's character by force. He can and will alter them—but only if the people will let Him. In that way He has really and truly limited His power. Sometimes we wonder why He has done so, or even wish that He hadn't. But apparently He thinks it worth doing. He would rather have a world of free beings, with all its risks, than a world of people who did right like machines because they couldn't do anything else. The more we succeed in imagining what a world of perfect automatic beings would be like, the more, I think, we shall see His wisdom.

Again, the freedom of a creature must mean freedom to choose: and choice implies the existence of things to choose between. A creature with no environment would have no choices to make: so that freedom, like self-consciousness (if they are not, indeed, the same thing) again demands the presence to the self of something other than the self.
The minimum condition of self-consciousness and freedom, then, would be that the creature should apprehend God and, therefore, itself as distinct from God. It is possible that such creatures exist, aware of God and themselves, but of no fellow-creatures. If so, their freedom is simply that of making a single naked choice--of loving God more than the self or the self more than God. But a life so reduced to essentials is not imaginable to us. As soon as we attempt to introduce the mutual knowledge of fellow-creatures we run up against the necessity of "Nature".

God created things which had free will. That means creatures which can go either wrong or right. Some people think they can imagine a creature which was free but had no possibility of going wrong; I cannot. If a thing is free to be good it is also free to be bad. And free will is what has made evil possible. Why, then, did God give them free will? Because free will, though it makes evil possible, is also the only thing that makes possible any love or goodness or joy worth having. A world of automata—of creatures that worked like machines—would hardly be worth creating. The happiness which God designs for His higher creatures is the happiness of being freely, voluntarily united to Him and to each other in an ecstasy of love and delight compared with which the most rapturous love between a man and a woman on this earth is mere milk and water. And for that they must be free.
