3:17 That the {e} man of God may be perfect, throughly furnished unto all good works.
(e) The Prophets and expounders of God's will are properly and distinctly called, men of God.
3:17 That the man of God. The preacher. See 1Ti 6:11 1Ki 13:1 2Ki 6:6.
May be perfect. Fully fitted for his work. The sense is complete (Revised Version).
Thoroughly furnished unto all good works. Fully equipped. If he is master of the Holy Scriptures, he is so equipped. If this was true when Paul wrote, with only a part of the New Testament written, with what emphasis may it be said now when we have both the Old Testament and New Testament in full!
3:17 That the man of God - He that is united to and approved of God. May be perfect - Blameless himself, and throughly furnished - By the scripture, either to teach, reprove, correct, or train up others.
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.
