God-Who-Forgives -Psalms 99:6-9

This promise talks about how God was faithful to Old Testament "heroes of the faith". The God that was faithful and forgiving to them is the same God that we serve.

"Moses and Aaron were among His priests, and Samuel was among those who called upon His name; They called upon the LORD, and He answered them. He spoke to them in the cloudy pillar; They kept His testimonies and the ordinance He gave them. You answered them, O LORD our God; You were to them God-Who-Forgives, though You took vengeance on their deeds. Exalt the LORD our God, and worship at His holy hill; For the LORD our God is holy."
