I believe, in the end, people will reap what they sow.  It is not for me to judge; that is up to the Lord.  Why do I believe such things?  Because the Scriptures tell me so.  Hang in and continue to “do good” to others.

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.  Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up.  Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers.

Galatians 6:7-16 (NIV)
