<quoted text>If you believe a hole opened up in his belly and literal water come out you are more ignorant of scripture than I thought.
Do you find anywhere in scripture that being a case of recieving the the Holy Spirit. The Living Water id the Spirit of Truth and that is what will proceed out the belly and heart/mind. His Holy Word washed away the old man and renews the mind guided by the Holy SPirit.
I have no reason not to believe him because just like you said, he does share God's truth with us so we know he's been reborn.
You can't it yet.
