13 and evil men and impostors shall advance to the worse, leading astray and being led astray. 14 And thou—be remaining in the things which thou didst learn and wast entrusted with, having known from whom thou didst learn, 15 and because from a babe the Holy Writings thou hast known, which are able to make thee wise—to salvation, through faith that 'is' in Christ Jesus;

Matthew Henry's Commentary on 2 Timothy 3:13-15

Commentary on 2 Timothy 3:10-13

(Read 2 Timothy 3:10-13)

The more fully we know the doctrine of Christ, as taught by the apostles, the more closely we shall cleave to it. When we know the afflictions of believers only in part, they tempt us to decline the cause for which they suffer. A form of godliness, a profession of Christian faith without a godly life, often is allowed to pass, while open profession of the truth as it is in Jesus, and resolute attention to the duties of godliness, stir up the scorn and enmity of the world. As good men, by the grace of God, grow better, so bad men, through the craft of Satan, and the power of their own corruptions, grow worse. The way of sin is down-hill; such go on from bad to worse, deceiving and being deceived. Those who deceive others, deceive themselves, as they will find at last, to their cost. The history of the outward church, awfully shows that the apostle spake this as he was moved by the Holy Ghost.

Commentary on 2 Timothy 3:14-17

(Read 2 Timothy 3:14-17)

Those who would learn the things of God, and be assured of them, must know the Holy Scriptures, for they are the Divine revelation. The age of children is the age to learn; and those who would get true learning, must get it out of the Scriptures. They must not lie by us neglected, seldom or never looked into. The Bible is a sure guide to eternal life. The prophets and apostles did not speak from themselves, but delivered what they received of God, 2 Peter 1:21. It is profitable for all purposes of the Christian life. It is of use to all, for all need to be taught, corrected, and reproved. There is something in the Scriptures suitable for every case. Oh that we may love our Bibles more, and keep closer to them! then shall we find benefit, and at last gain the happiness therein promised by faith in our Lord Jesus Christ, who is the main subject of both Testaments. We best oppose error by promoting a solid knowledge of the word of truth; and the greatest kindness we can do to children, is to make them early to know the Bible.
