Do not be deceived: God cannot be mocked. A man reaps what he sows. Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life.

Galatians 6:7-8

Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously.

2 Corinthians 9:6
