Do you admit your response contradicts Scripture? It works 'sometimes?' Let me cut you off before you respond here. Let's assume that God is not a 'slot machine', and does not answer to 'sinful requests.' Surely the request of a true Christian, asking that He merely contact a skeptic/seeker/doubter, is not off limits, is it?.?.?.?
“Ask and it will be given to you; seek and you will find; knock and the door will be opened to you."
"If you believe, you will receive whatever you ask for in prayer"
"Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours"
Wow! You have already spent much more time in this thread, then you ever would in a simple prayer request. In fact, the request will take you all of 5 seconds.... Are you going to? If not, why not?
All these assertions are unfounded and appear blank to me. Anecdotal testimonials are a dime a dozen. I trust you realize 'God claims' come from around the world; many even from opposing faiths. Please perform this 5 second request of intercessory prayer. If you will not, why won't you?
Please look up 'external world skepticism'. Please understand that any experience you receive, has an infinite number of plausible sources to attribute and consider. It's interesting how you ruled out all the others so easily? Or maybe you never even considered the possibility of all the others????
