Galatians 6:7-9

7Do not be deceived: God cannot be mocked. A man reaps what he sows. 8Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life. 9Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up.
