8 The word [is] faithful, and I desire that thou insist strenuously on these things, that they who have believed God may take care to pay diligent attention to good works. These things are good and profitable to men.
9 But foolish questions, and genealogies, and strifes, and contentions about the law, shun; for they are unprofitable and vain. 10 An heretical man after a first and second admonition have done with, 11 knowing that such a one is perverted, and sins, being self-condemned.
Matthew Henry's Commentary on Titus 3:8-11
Commentary on Titus 3:8-11
(Read Titus 3:8-11)
When the grace of God towards mankind has been declared, the necessity of good works is pressed. Those who believe in God, must make it their care to maintain good works, to seek opportunities for doing them, being influenced by love and gratitude. Trifling, foolish questions must be avoided, and subtle distinctions and vain inquiries; nor should people be eager after novelties, but love sound doctrine which tends most to edifying. Though we may now think some sins light and little, if the Lord awaken the conscience, we shall feel even the smallest sin heavy upon our souls.
