Seth Godin defines remarkable better than anyone, including Webster... remarkable means people are going to make a remark.
Here's a snippet from his post How to be remarkable:
Remarkable doesn't mean remarkable to you. It means remarkable to me. Am I going to make a remark about it? If not, then you're average, and average is for losers.This applies to churches, classes, preachers, teachers, and even members. Folks don't "go into the highways and byways and compel them" when their church, class, preacher, or teacher is average.
If people remark, then the church is remarkable. If not, it's average.
Somebody, somewhere may be thinking, "I need to tell my people to start remarking."
Understand that people naturally remark about the truly remarkable.
