Christ Has Commissioned You with His Keys
John 20:21-23
Jesus gave the binding and loosing keys to the church after his resurrection when he appeared to the disciples and other believers. We use the binding key (the Law) when someone is embracing a sin to show them they are damned to Hell and need a savior, and we use the loosing key (the Gospel) when they repent to forgive them of that sin and tell them Jesus is their savior.
