If faith works how every religion says it works......

[Thor]

Actually now that you mention it, the only rational way to test Christianity is to diligently test what Jesus actually said and promised, and see if it does what he says it will.

Okay, Rad, let's test Christianity!

The Bible tells us Jesus said this:

John 14:12-14

14:12 Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father.
14:13 And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. (14:13-14)
14:14 If ye shall ask any thing in my name, I will do it.

Here Jesus says that if you believe in him and ask for "anything" in his name, he "will do it".

Let's gather some people who believe in Jesus and have them ask that all the blind people on Earth be given 20/20 eyesight.

If Christianity is true, every blind person should promptly have perfect vision!

Whaddya say? Get some of your Jesus loving buddies and ask Jesus to do this. According to the Bible, he'll do it!

Is that a good enough test?

(Cue the rationalizing why this isn't a "proper test" is 3...2....1....)
