Conventional wisdom says

life will be better if you keep everything you have for yourself. However, God clearly says that your life will be better if you work to make another person's life better.

In Galatians 6:7-9, Paul writes, 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.
