Repent is not a forbidden word. Though you might think differently if you sat in a church and the word never comes up.
Jesus preached that we must repent:
Matthew 4:17 From that time, Jesus began to preach, and to say, “Repent! For the Kingdom of Heaven is at hand.”
Jesus called sinners to repent:
Matthew 9:13 But you go and learn what this means: ‘I desire mercy, and not sacrifice,’ for I came not to call the righteous, but sinners to repentance.”
Jesus denounced cities that did not repent at his message:
Matthew 11:20 Then he began to denounce the cities in which most of his mighty works had been done, because they didn’t repent.
Jesus said there was joy in heaven over a sinner who repented:
Luke 15:7 I tell you that even so there will be more joy in heaven over one sinner who repents, than over ninety-nine righteous people who need no repentance.
Jesus told church members to repent:
Revelation 3:19 As many as I love, I reprove and chasten. Be zealous therefore, and repent.
Is there any sin in our lives that we need to repent of? Remember, Jesus is just a prayer away.
