"... new birth does not come about by natural causes or the operations of nature but by God’s immediate power. He alone has the capacity to do it. Further, it is supernatural in the sense of being beyond man’s mutilated and depraved condition by nature ... Regeneration is possible only by a supernatural work of God."
From my book What the Bible teaches about being born again, pp 34, 35
9. To believe in something you cannot prove
Should not be thought of as wrong
But to give a reason why you believe
Is a thing for which you should long
3. Don't answer a fool or like him you'll be, Answer a fool or conceited he'll be. (Proverbs 26 verses 4 and 5.)
But how can I at the answer arrive As to which of these verses here applies? It's a thing on which it's hard to be wise.
