Galatians 6:6-10

6:6-10 He who is being instructed in the word must share in all good things with him who is giving instruction. Don't deceive yourselves; no one can make a fool of God; whatever a man sows this he will also reap. He who sows to his own lower nature will from that nature reap a blighted harvest. He who sows to the Spirit will from the Spirit reap life eternal. Don't get tired of doing the fine thing, for, when the proper time comes, we will reap so long as we don't relax our efforts. So then, as we have opportunity, let us do good to all, especially to those who are members of the household of the faith.

Here Paul becomes intensely practical.

The Christian Church had its teachers. In those days the Church was a really sharing institution. No Christian could bear to have too much while others had too little. So Paul says, "If a man is teaching you the eternal truths, the least you can do is share with him such material things as you possess."

He goes on to state a grim truth. He insists that life holds the scales with an even balance. If a man allows the lower side of his nature to dominate him, in the end he can expect nothing but a harvest of trouble. But if he keeps on walking the high way and doing the fine thing, in the end God will repay.

Christianity never took the threat out of life. The Greeks believed in Nemesis; they believed that, when a man did a wrong thing, immediately Nemesis was on his trail and sooner or later caught up. All Greek tragedy is a sermon on the text, "The doer shall suffer." What we do not sufficiently remember is this--it is blessedly true that God can and does forgive men for their sins, but not even he can wipe out the consequence of sin. If a man sins against his body, soon or late he will pay in ruined health--even if he is forgiven. If a man sins against his loved ones, soon or late hearts will be broken even if he is forgiven. John B. Gough, the great temperance orator, who had lived a reckless early life, used to declare in warning, "The scars remain." And Origen, the great Christian scholar and a universalist, believed that, although all men would be saved, even then the marks of sin would remain. We cannot trade on the forgiveness of God. There is a moral law in the universe. If a man breaks it he may be forgiven, but, nonetheless, he breaks it at his peril.

Paul finishes by reminding his friends that sometimes the duty of generosity may be irksome, but no man who ever cast his bread upon the waters found that it did not return some day to him.
