Forgiveness: Automatic or conditional?

Greetings to all. Thanks for inviting me, Ron, and accepting me, Randal. I hope to post to TFR as time permits.

I’m in the midst of a friendly discussion with a brother that I thought I’d share briefly. Is forgiveness toward a fellow human to be granted automatically or is it conditional in some way? My friend maintains the former per Mark 11:25,26. However, I have always taught the latter according to Luke 17:3,4. Obviously, Scripture must be harmonized, and I believe these passages do not contradict–when properly understood. Your thoughts regarding how to harmonize them?

P.S. After sharing your own thoughts, feel free to read mine on AE:
