You know what God gave up to reveal the truth to us? He gave us His Son. His Son died to save us from our sins, and yet people are willing to believe a national news source instead of the Bible. Just think about that.
Holding on to our heartbreaking pasts is destructive behavior, and we need to stop doing this for the sake of our current relationships.
Sometimes we may feel useless, but God has blessed every one of us with a talent.
