I Corinthians 8:3

But if any man love God - In that way which the commandment requires, which will necessarily beget love to his neighbor, the same is known of him - is approved of God, and acknowledged as his genuine follower.

love God--the source of love to our neighbor (Jo1 4:11-12, Jo1 4:20; Jo1 5:2). the same--literally, "this man"; he who loves, not he who "thinks that he knows," not having "charity" or love (Co1 8:1-2). is known of him--is known with the knowledge of approval and is acknowledged by God as His (Psa 1:6; Gal 4:9; Ti2 2:19). Contrast, "I never knew you" (Mat 7:23). To love God is to know God; and he who thus knows God has been first known by God (compare Co1 13:12; Pe1 1:2).

But if any man love God,.... As they do, and show it, who love their brethren, and are careful not to grieve them; and make use of their superior knowledge, not for their destruction, but edification: the same is known of him; is taught by him, made to know more by him; such an one increases in spiritual knowledge, or he is highly approved of, esteemed, and beloved by God: he takes a special and particular notice of him, manifests his love to him, and will own and acknowledge him another day, when proud, haughty, overbearing, and hard hearted professors, will be rejected by him.

The apostle, in this chapter, answers another case proposed to him by some of the Corinthians, about eating those things that had been sacrificed to idols. I. He hints at the occasion of this case, and gives a caution against too high an esteem of their knowledge (Co1 8:1-3). II. He asserts the vanity of idols, the unity of the Godhead, and the sole mediation of Christ between God and man (Co1 8:4-6). III. He tells them that upon supposition that it were lawful in itself to eat of things offered to idols (for that they themselves are nothing), yet regard must be had to the weakness of Christian brethren, and nothing done that would lay a stumbling block before them, and occasion their sin and destruction (Co1 8:7 to the end).
