Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. —2 Corinthians 5:17
I insist that the new birth was provided in the love and grace and wisdom of God in order to draw a sharp line between those who acquire Christianity by any other method and those who have experienced regenesis….
[S]ome professing Christians are still trying to find natural and reasonable explanations for that which God has said He would do miraculously by His Spirit.
Let me warn you that if you are a Christian believer and you have found a psychologist who can explain to you exactly what happened to you in the matter of your faith, you have been unfrocked!…The honest psychologist can only stand off respectfully and say, “Behold the works of the Lord.”
He never can explain it! ICH035-036
The humblest Christian is called to live a miracle, a life that is a moral and spiritual life with such intensity and such purity that no human being can do it—only Jesus Christ can do it. TTPI, Book 2/060
[T]he…genuine child of God is someone who cannot be explained by human reasoning. TTPI, Book 3/047
