Saul of Tarsus was a murderer. Zacchaeus was a tax collector. Mary Magdalene had seven demons. Judas Iscariot was a deceiver, etc.
Further, the Old Testament is full of God's people behaving badly. Sampson was prideful and made a poor life choice trusting Delilah. Cain burned with self pity and killed his brother, Abel. Adam and Eve made the worst decision possible by defying God's instruction in the Garden of Eden. King David had an affair with a woman then had her husband killed.
Jesus is the Lord (and Savior) of the destructive. He chose them and saved them. He does the same today! No one is beyond His reach or hidden from His mercy, grace, and forgiveness. His light can touch even the deepest depths, darkest places, and hardest of hearts. There is no one exempt from His reign as King...though there are some who do not acknowledge his rule and authority.
The Lord is near to the brokenheartedand saves the crushed in spirit. (Psalm 34:18 ESV)
Why did Saul hate Christians so much? What made Zacchaeus decide to be a tax collector? Each of us is a broken person. All of us have a story to tell and need Jesus...an everlasting life is just icing on the cake.
"I know that you can do all things, and that no purpose of yours can be thwarted.... I had heard of you by the hearing of the ear, but now my eye sees you; therefore I despise myself,and repent in dust and ashes." (Job 42:2, 5, 6 ESV)
