1 Corinthians 8:3

But if any man love God, the same is known of Him.

In this chapter the apostle offers the answer to a second question which had been laid before him by the Corinthian Christians: Was it right for a Christian to eat flesh that had been offered in sacrifice to an idol? The situation was somewhat complicated, since the entire public and social life of the people of Corinth and of the citizens of all the large cities in those days was permeated with, and to some extent governed by, the worship of idols. Feasts and banquets, both public and private, were usually connected with the name of some heathen god. A large part of the meat on sale in the shops and therefore found on the average table came from the temples, and so it became a difficult matter to avoid its use. This explains the perplexity of the Corinthians which caused their question to the apostle. Before giving his real answer, he reminds them, in the form of a parenthesis, of certain basic facts. With a tinge of sarcasm he writes that he is aware of the fact that all claimed the possession of knowledge. They all were sure that they needed no more information as to the fundamentals of Christianity. Paul proceeds to correct this idea: Knowledge puffs up, inflates, but love builds up. Many of the Corinthian Christians, as many believers are doing today, pretended to be so firmly grounded in head knowledge that they rose superior to all prejudices. But the result was an amount of proud self-satisfaction which forgot all considerations for their neighbor. And therefore Paul frankly tells his readers that such an attitude, according to which a person believes himself to be above all heathen superstition and to have the full and complete knowledge of God and His essence, is vain and sinful if it is not attended by the proper fruit of love in good works.

This axiomatic saying the apostle amplifies: But if anyone has the idea that he knows something (he is herewith definitely told that) he has never yet learned as he ought to, he has not yet obtained the real basis of true knowledge. Just as soon as a person shows any conceit as to his spiritual knowledge, this fact proves that he is still far from possessing that full, deep, penetrating, exhaustive knowledge which is contained in Christianity. For the more a person in all humility and under the gracious guidance of God studies the wonderful doctrines which God has given to men in His Word of grace, the more this humility must increase, the more he will confess: We know in part only, and a very small part at that. Self-conceit and real knowledge are incompatible in spiritual things. On the other hand: But if any one loves God, this person is known of Him. If the faith of a Christian has found its proper expression in love toward God, from which flows love toward his neighbor, 1 John 5:2, then he also knows that his knowledge of love is the result of God's having known him. If God knows anyone in this way, it is an effective knowledge, Galatians 4:9; Romans 8:29, it brings him into communion, into sonship, with God, into the most intimate relation of mind and spirit. Naturally this includes also this that every person that is the subject of such an effective knowledge on the part of God will know God in turn, will grow in knowledge day by day until the day of the consummation of all hopes and knowledge. To know God as Him that has known us in Christ, that is the childlike knowledge which does not puff up, but is, on the contrary, a constant spur to us to imitate the great love of God which bent down to us in our misery and wretchedness and brought us salvation.
