David was God’s chosen man to rule as king of Israel. But David was a deeply flawed man who slept with a married woman and then had her husband killed to cover his transgression. He then rose up and presided over a great kingdom for God, from whom God built an eternal dynasty.
Peter hung out with Jesus. He saw all the miracles, as well as the transfiguration. A few days later Peter denied knowing Jesus three times. God then built the church through Peter.
James, the half-brother of Jesus was not an original believer in Jesus deity. The resurrection changed James and God used him as a church leader.
It is not how well or how many mistakes you make in life, but rather if you have the fortitude and character to own your mistakes and then give of yourself to God!
Little can become much when you allow God to be your focus and pursuit. Never fear the potters wheel, rather fear never making it on to the wheel!
