Galatians 6:3-8

For if a man thinketh himself to be something when he is nothing, he deceiveth himself. But let each man prove his own work, and then shall he have his glorying in regard of himself alone, and not of his neighbor. For each man shall bear his own burden. But let him that is taught in the word communicate unto him that teacheth in all good things. Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. For he that soweth unto his own flesh shall of the flesh reap corruption; but he that soweth unto the Spirit shall of the Spirit reap eternal life.
