Why do I keep seeing these free will arguments?

B/c we keep challenging their faith in many different ways (from a big intellectual menu)with logic, science and common sense and they try to give answers but their answers come from a much shorter menu of 1)Gods will 2)Free will 3)Bible says so and 4)here's a half ed attempt at reason, logic or science.We have great trouble enlightening some of them but we keep it up b/c we care about the ones 'on the fence'.
