6:20 {13} O Timothy, keep that which is committed to thy trust, avoiding profane [and] vain babblings, and oppositions of science falsely so called:
(13) He repeats the most important of all the former exhortations, which ought to be deeply imprinted in the minds of all ministers of the word, that is, that they avoid all vain babblings of false wisdom, and continue in the simplicity of sincere doctrine.
6:20,21 O Timothy, keep that which is committed to thy trust. A final exhortation to faithfully discharge his trust.
Oppositions of science. The wild speculations which were already taught by dreamers and which were probably derived from Jewish sources. These speculations and departed from the faith. There are allusions in the Epistles to Ephesus and Colosse to the germs of the same false teaching.
6:20 Keep that which is committed to thy trust - The charge I have given thee, 1Tim 1:18. Avoid profane empty babblings - How weary of controversy was this acute disputant! And knowledge falsely so called - Most of the ancient heretics were great pretenders to knowledge.
6:17-21 Being rich in this world is wholly different from being rich towards God. Nothing is more uncertain than worldly wealth. Those who are rich, must see that God gives them their riches; and he only can give to enjoy them richly; for many have riches, but enjoy them poorly, not having a heart to use them. What is the best estate worth, more than as it gives opportunity of doing the more good? Showing faith in Christ by fruits of love, let us lay hold on eternal life, when the self-indulgent, covetous, and ungodly around, lift up their eyes in torment. That learning which opposes the truth of the gospel, is not true science, or real knowledge, or it would approve the gospel, and consent to it. Those who advance reason above faith, are in danger of leaving faith. Grace includes all that is good, and grace is an earnest, a beginning of glory; wherever God gives grace, he will give glory.
