Galatians 6:7-9

6:7 Do not be deceived. God will not be made a fool. For a person will reap what he sows, 6:8 because the person who sows to his own flesh will reap corruption from the flesh, but the one who sows to the Spirit will reap eternal life from the Spirit. 6:9 So we must not grow weary in doing good, for in due time we will reap, if we do not give up.
