Psalms 95:10

Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it. For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it. For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world. For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works. And in this place again, If they shall enter into my rest. Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief: Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts. [Psalms 95:7-11] For if Jesus had given them rest, then would he not afterward have spoken of another day. There remaineth therefore a rest to the people of God. For he that is entered into his rest, he also hath ceased from his own works, as God did from his. Let us labour therefore to enter into that rest, lest any man fall after the same example of unbelief. For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. Neither is there any creature that is not manifest in his sight: but all things are naked and opened unto the eyes of him with whom we have to do.

"See, O people, the grace of Christ about you. Even while you are harassed on earth, you have possessions in heaven. There, then, let your heart be, where your possession is." This is the rest that is due the just and is denied the unworthy. Wherefore says the Lord, "As I swore in my wrath, that they shall not enter into my rest." For they who have not known the ways of the Lord shall not enter into the rest of the Lord, but to the individual who has fought the good fight and has finished his course it is said, "Turn to your rest." It is a blessed rest to pass by the things of the world and to find repose in the celestial fellowship of the mysteries that are above the world. This is the rest toward which the prophet hastened, saying, "Who will give me wings like a dove and I will fly and be at rest?" The holy person knows that his rest is in heaven, and to this rest he says his soul must turn. Therefore his soul was in its rest, to which he says it must return. This is the rest of the great sabbath, in which each of the saints is above the sensible things of the world, devoting himself entirely to deep and invisible mystery and cleaving to God. This is that rest of the sabbath on which God rested from all the works of his world.

Did not the prophet, speaking in behalf of God, say to you, "Forty years I was offended with that generation, and I said, 'These always err in heart.' " How was it, then, that at that time God did not turn away from you? How is it that after you killed your children, after your idolatries, after your many acts of arrogance, after your unspeakable ingratitude, that God even allowed the great Moses to be a prophet among you and that he worked wondrous and marvelous signs himself? What happened in the case of no human being did happen to you. A cloud was stretched over you in place of a roof; a pillar instead of a lamp served to guide you; your enemies retreated of their own accord; cities were captured almost at the first battle shout. You had no need of weapons, no need of an army in array, no need to do battle. You had only to sound your trumpets, and the walls came tumbling down of their own accord. And you had a strange and marvelous food that the prophet spoke of when he exclaimed, "God gave them the bread of heaven. The people ate the bread of angels; he sent them provisions in abundance."

"Forty years long was I very near unto this generation, and said, It is a people that do always err in their hearts; for they have not known My ways" [Psalm 95:10]. The forty years have the same meaning as the word "always." For that number forty indicates the fullness of ages, as if the ages were perfected in this number. Hence our Lord fasted forty days, forty days He was tempted in the desert, [Matthew 4:1-11] and forty days He was with His disciples after His resurrection. [Acts 1:3] On the first forty days He showed us temptation, on the latter forty days consolation: since beyond doubt when we are tempted we are consoled. For His body, that is, the Church, must needs suffer temptations in this world: but that Comforter, who said, "Lo, I am with you always, even unto the end of the world," [Matthew 28:20] is not wanting. For this was I with them forty years, to show such a race of men, which always provokes Me, even unto the end of the world: because by those forty years He meant to signify the whole of this world's duration.
