Mankind faces a singular problem. People are broken and the world is broken because our friendship with God has been broken, ruined by human rebellion. Humans, you and I—are guilty, enslaved, lost, dead. All of us. Everyone. Everywhere. The guilt must be punished, the debt must be paid, the slave must be purchased. Promising better conduct in the future will not mend the crimes of the past. No, a rescuer must ransom the slaves, a kindred brother must pay the family debt, a substitute must shoulder the guilt. There is no other way of escape.
This is why Jesus of Nazareth is the only way to God, the only possible source of rescue. He is the only one who solved the problem.
