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, 2Pe 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.
14. But … thou—Whatever they may do. Resuming the thread begun at 2Ti 3:10.
learned—from me and thy mother and grandmother (2Ti 1:5; 2:2).
assured of—from Scripture (2Ti 3:15).
of whom—plural, not singular, in the oldest manuscripts, "from what teachers." Not only from me, but from Lois and Eunice.
