V.1 We know we are in “the latter times” because those who once professed faith, and were considered Christians, are departing from the faith. We hear of men in pulpits today who claim to be Christian men, but who deny the faith. Probably the greatest danger among believers today is the giving up of the absolute authority of the Word of God.
V.3 Let us beware of any teaching that is not according to God’s Word, even though it may seem to be very pious and religious.
V.6 Three times from here to the end of the chapter “doctrine” is mentioned. To be able to detect false doctrine, the word means “what is taught,” we need to be well acquainted with “good doctrine.” The more you live the truth you know, the more you will be able to detect error.
V.8 Bodily exercise, profits just for a little time. But godliness is profitable unto all things, here and for eternity. No doubt Paul got plenty of bodily exercise in his endless work for the Lord and His people!
V.10 In the verse the word “Savior” does not mean Savior from sins, but “Preserver” or the one who gives and sustains life.
V.12 Timothy is told how to behave so that he will not be despised — this would be so if his conduct was consistent with what he was teaching.
V.13-16 Let us be diligent in reading and meditating; first for our own need and then to help others.
