Galatians 6:7-9

7Do not be deceived, God is not mocked [He will not allow Himself to be ridiculed, nor treated with contempt nor allow His precepts to be scornfully set aside]; for whatever a man sows, this and this only is what he will reap.

8For the one who sows to his flesh [his sinful capacity, his worldliness, his disgraceful impulses] will reap from the flesh ruin and destruction, but the one who sows to the Spirit will from the Spirit reap eternal life.

9Let us not grow weary or become discouraged in doing good, for at the proper time we will reap, if we do not give in.
