I'm a Christian who enjoys (what I consider to be healthy) relations with several good friends who are Muslim, and simultaneously have strong support for several missionary friends who are carrying the gospel of Jesus Christ far and wide, including into areas that are heavily Muslim.
I love having these relationships and yet, have to admit that I've not thought a lot about the interaction of theology between these folks. So, I've just come across this blog (His Peace Upon Us : https://hispeaceuponus.wordpress.com/), and thought I'd share the resource as I continue to muse about the things I'm reading there.
