Without the grace of God, we would all be left in utter darkness. The last thing we should ever do is judge someone harshly when they are seeking to repent and rehabilitate their lives.
There are many that want to enjoy the benefits of the kingdom but they want to do it on their terms and without changing their behavior. This is not the sign of a disciple.
God and His church rejoice when one of His children turns back to God and follows Jesus. We should reconcile our minds to this fact and rejoice as well.
