“My theory is that it can be explained in our physical world as a DMT-based psychedelic experience”
The problem with your theory is it does not stand up to facts. In the case of the good Dr....he was braindead...no brainwaves at any level. You cannot have the kind of experience your hypothesizing on without brainwave activity.
Second, as one who has experienced NDE I can tell you with certainty it is not hallucination. I have hallucinated with LSD, etc. when younger. There is a huge difference. If you believe that the NDE is a hallucination, then you need to contemplate your entire existence as a hallucination...seriously. It is that real.
I find non Christians have a difficult time with believing that God actually does exist and is alive right now. God does communicate with those who are with him regularly. We do not have to die to speak with God or indeed to hear from Him.
I agree. I think a good way to look at it is the unbelievers need to see to believe (seeing is believing, the saying goes). But Christians know that it is the other way around, believing is seeing. In the book of Hebrews 11:6, the writer says that:
But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
God rewards those who come to Him in faith, not needing to see first before believing in Him. It is only then that God rewards that faith with more than enough evidence to satisfy those who diligently seek Him. I KNOW that it is true - I have seen way too much proof to ever be able to turn my back on God or cast away my faith.
