2 Timothy 1:3

He must be clean from all the passions who is to hunt after the truth: for whoso is freed from these shall be freed also from his error and attain unto the truth. Wherefore saith Peter, "Of a truth I perceive that God is no respecter of persons; but in every nation he that feareth Him, and worketh righteousness, is acceptable to Him:" that is, He calls and attracts him unto the truth. Peter calls the man irreproachable in all things one that "worketh righteousness," and Paul says "touching the righteousness which is in the law found blameless." Again, "I give thanks to God, whom I serve from my forefathers with a pure conscience." How then, you will say, were unclean persons considered worthy of the Gospel? Because they wished and longed for it. Thus the one sort, though in error, are attracted by Him, because they are clean from passions; the others, of their own accord approaching, are not thrust back. Many also even from their ancestors have received the true religion.

"I thank God, whom I serve from my forefathers with pure conscience, that without ceasing I have remembrance of thee in my prayers night and day; greatly desiring to see thee, being mindful of thy tears, that I might be filled with joy." "'I thank God,' he says, 'that I remember thee,' so much do I love thee." This is a mark of excessive love, when a man glories in his affection from loving so much. "I thank God," he says, "Whom I serve": and how? "With a pure conscience," for he had not violated his conscience. And here he speaks of his blameless life, for he everywhere calls his life his conscience. Or because I never gave up any good that I purposed, for any human cause, not even when I was a persecutor. Wherefore he says, "I obtained mercy, because I did it ignorantly in unbelief" (1 Tim. i. 13); all but saying, "Do not suspect that it was done of wickedness." He properly commends his own disposition, that his love may appear sincere. For what he says is in fact, "I am not false, I do not think one thing and profess another." So in the book of Acts we read he was compelled to praise himself. For when they slandered him as a seditious man and an innovator, he said in his own defense, "Ananias said to me, The God of our fathers hath chosen thee that thou shouldest know His will, and see that Just One, and shouldest hear the voice of His mouth. For thou shalt be His witness unto all men of what thou hast seen and heard." (Acts xxii. 14, Acts xxii. 15) In the same manner here, that he may not, as if he had been forgetful, have the character of one void of friendship and conscience, he justly praises himself, saying, that "without ceasing I have remembrance of thee," and not simply that, but "in my prayers." That is, it is the business of my prayers, that which I constantly continue to perform. For this he shows by saying, "For this I besought God day and night, desiring to see thee." Mark his fervent desire, the intensity of his love. And again, his humility, how he apologizes to his disciples, and then he shows that it was not on light or vain grounds; and this he had shown us before, but again gives proof of it. "Being mindful of thy tears." It was natural for Timothy, when parting from him, to mourn and weep, more than a child torn away from the milk and from the breast of its mother. "That I may be filled with joy; greatly desiring to see thee." I would not willingly have deprived myself of so great a pleasure, though I had been of an unfeeling and brutal nature, for those tears coming to my remembrance would have been enough to soften me. But such is not my character. I am one of those who serve God purely; so that many strong motives urged me to come to thee. So then he wept. And he mentions another cause, and that of a consolatory kind.
