Verse 3. But if any man love God. If any man is truly attached to God; if he seeks to serve him, and to promote his glory. The sense seems to be this: "There is no true and real knowledge which is not connected with love to God. This will prompt a man also to love his brethren, and will lead him to promote their happiness. A man's course, therefore, is not to be regulated by mere knowledge, but the grand principle is love to God and love to man. Love edifies; love promotes happiness; love will prompt to what is right; and love will secure the approbation of God." Thus explained, this difficult verse accords with the whole scope of the parenthesis, which is to show that a man should not be guided in his intercourse with others by mere knowledge, however great that may be; but that a safer and better principle was love, charity, (agaph) whether exercised towards God or man. Under the guidance of this, man would be in little danger of error. Under the direction of mere knowledge, he would never be sure of a safe guide. See 1 Co 13.

The same is known of him. The words "is known," (egnwstai,) I suppose to be taken here in the sense of "is approved by God; is loved by him; meets with his favour," etc. In this sense the word known is often used in the Scriptures. See Barnes "Mt 7:23".

The sense is, "If any man acts under the influence of sacred charity, or love to God, and consequent love to man, he will meet with the approbation of God. He will seek his glory, and the good of his brethren; he will be likely to do right; and God will approve of his intentions and desires, and will regard him as his child. Little distinguished, therefore, as he may be for human knowledge, for that science which puffs up with vain self-confidence, yet he will have a more truly elevated rank, and will meet with the approbation and praise of God. This is of more value than mere knowledge, and this love is a far safer guide than any mere intellectual attainments. So the world would have found it to be if they had acted on it; and so Christians would always find it.
