15 Then he returned to the man of God, he and all his company, and he came and stood before him. And he said, "Behold, I know that there is no God in all the earth but in Israel; so accept now a present from your servant."
The mercy of the cure affected Naaman more than the miracle. Those are best able to speak of the power of Divine grace, who themselves experience it. He also shows himself grateful to Elisha the prophet. Elijah refused any recompence, not because he thought it unlawful, for he received presents from others, but to show this new convert that the servants of the God of Israel looked upon worldly wealth with a holy contempt. The whole work was from God, in such a manner, that the prophet would not give counsel when he had no directions from the Lord. It is not well violently to oppose the lesser mistakes which unite with men's first convictions; we cannot bring men forward any faster than the Lord prepares them to receive instruction. Yet as to us, if, in covenanting with God, we desire to reserve any known sin, to continue to indulge ourselves in it, that is a breach of his covenant. Those who truly hate evil, will make conscience of abstaining from all appearances of evil.
