Galatians 6:8-9

8A person may do things only to make himself happy. That person's harvest will be God's punishment and death. Or a person may do the things that God's Spirit wants. That person will receive a harvest from God's Spirit. The harvest will be life with God for ever.

9We must continue to do things that are good and we should not get tired. If we do not feel weak and stop doing good things, then we will receive a good harvest at the proper time.
