His response: of course it makes perfect sense! Satan wants to mislead you away from the organization.
My response: Is Satan more powerful than God?
Expected reply: Definitely not!
My response: Well, if Satan can mislead me AFTER I specifically prayed to God asking him to convince me BEYOND DOUBT if JW's have the truth, then I can come to either one of two conclusions: 1. Satan is more powerful than God, OR 2. JW's are not the true religion and do not have God's backing, this is why God is NOT convincing me beyond doubt that JW's have the truth!
Which of the above makes more sense to you?
