1 Thessalonians 3:8

Let us imagine a person occupying a place of honor in a king’s court. He possesses vast wealth, great power, a birthplace excelling others, distinguished ancestors and the admiration of all people. Examine the matter. Is not this person more of a slave than all others? And let us compare him to not merely a slave but a slave’s slave—for many servants have slaves.… But our circumstances are different. If one fares poorly, there are many to grieve with him. Should he obtain distinction, many to find pleasure with him. Not so with the apostle Paul. “For if one member suffers, all the members suffer; or if one member is honored, all the members rejoice.” Paul’s words of admonition vary with the situation. “What is my hope or joy? Are not you it?” At another, “Now we live, if you stand fast in the Lord”; at another, “Out of much affliction and anguish of heart I wrote unto you”14; and “Who is weak, and I am not weak? Who is offended, and I burn not?”

The attitude of a teacher should be such as to regard his disciples as everything. “Now we live,” Paul says, “if you stand fast in the Lord.” And again, “What is our hope, or joy, or crown of rejoicing? Is it not even you in the presence of our Lord Jesus Christ?” You see Paul’s concern in this matter, his regard for the good of his disciples, not less than for his own. For teachers ought to surpass natural parents, to be more zealous than they. And it is right for their children to show deep affection for them. For he says, “Obey those that rule over you, and submit yourselves; for they watch for your souls as they that must give account.”

"For this cause, brethren, we were comforted over you in all our distress and affliction through your faith: for now we live, if ye stand fast in the Lord."

What is comparable to Paul, who thought the salvation of his neighbors was his own, being so affected towards all, as really towards members? He did not require them to be thankful to him for the trials which he suffered for them, but he was thankful to them that they were not moved on account of his trials. As if he had said, that to you rather than to us was injury done by those trials; you were tempted rather than we, you who suffered nothing, rather than we who suffered. Because, he says, Timothy brought us these good tidings, we feel nothing of our sorrows, but were comforted in all our affliction; not in this affliction only. For nothing besides can touch a good teacher, as long as the affairs of his disciples go on to his mind. Through you, he says, we were comforted; you confirmed us. And yet the reverse was the case. For that when suffering they did not yield, but stood manfully, was sufficient to confirm the disciples. But he reverses the whole matter, and turns the encomium over to them. You have anointed us, he says, you have caused us to breathe again; you have not suffered us to feel our trials. And he has not said, we breathe again, nor we are comforted, but what? "Now we live," showing that he thinks nothing is either trial or death, but their stumbling, whereas their advancement was even life. How else could any one have set forth either the sorrow for the weakness of one's disciples, or the joy? He has not said we rejoice, but "we live," the life to come.

So that without this we do not even think it life to live. So ought teachers to be affected, so disciples; and there will be nothing at any time amiss.

This is why I am admonishing your graces and urging you in the Lord to think lightly, my brothers and sisters, of things present, which you can’t carry with you when you die. Be on your guard against sin, on your guard against injustice of all sorts, on your guard against worldly appetites and greed. It is only then, you see, that our profit from you is undiminished and our reward full of joy in the Lord. I mean, we say what has to be said. We preach what has to be preached and absolve ourselves of our debt to the Lord in the Lord’s sight. We haven’t kept quiet about what we fear, and haven’t kept quiet about what we love. So the sword of the Lord’s vengeance, upon whomever it may fall, cannot blame the sentinel for failing at his post. Still, we don’t want our reward to be assured with all of you being lost, but with all of you being found. The apostle Paul too was sure of his reward, and yet what did he say to the people? “Now we live, if you stand fast in the Lord.”

He did not say: we were comforted, but: "we live," showing by this that their stumbling he considers death for himself, and their progress, standing, and firmness in Christ – life.

For now we live, if you stand fast in the Lord, as if saying: I value your condition so highly that I think it sustains me: "It is enough; Joseph my son is still alive" (Gen. 45:28).
