The Happiness of Heaven in the Repentance of Sinners
Thabiti Anyabwile gives a sermon from Luke 15 where Jesus tells three parables about the joy in finding something that was lost: a coin, a sheep, a son. Something similar happens in heaven when a sinner repents of their sin and trusts in Christ, when a sheep returns to the Good Shepherd. This heavenly happiness is eternal and unmitigated. So as we evangelize, calling for Spirit-wrought repentance, we understand this call to true repentance is a call to true joy.
