You reap wat you sow

Do not be deceived: God cannot be mocked. A man reaps what he sows.
The one who sows to please his sinful nature, from that nature will
reap destruction; the one who sows to please the Spirit, from the
Spirit will reap eternal life. Let us not become weary in doing good,
for at the proper time we will reap a harvest if we do not give up.

Galatians 6:7-9 (New International Version)
