Forgive because you've been forgiven much

Forgiveness isn't a one-time thing.

If My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land. - 2 Chronicles 7:14

You do not stay angry forever but delight to show mercy. - Micah 7:18
