Galatians 6:4-8

But let each one test his own work, and then his reason to boast will be in himself alone and not in his neighbor. For each will have to bear his own load. Let the one who is taught the word share all good things with the one who teaches. Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life.
