102 Should we Forgive the Unrepentant? (Matthew 6:12, 14-15; 18:15-20)

Sermon Update 4.27.21. This lesson falls on the heals of my Daily Bread and Forgiveness sermon (in the Sermon on the Mount series). I look more at the idea of Yahweh repaying us in return of how we treat others, and then I move into the issue of people walking in unrepentance. It's sometimes taught that we have to forgive others even when they don't repent, but is this proper?
