Nothing, it seems to me, is quite so strange as the way in which man by nature always objects to the doctrine of regeneration. There is nothing also, I sometimes think, that so demonstrates the depth of sin in the human heart as this objection to the doctrine of the rebirth or being born again. Read the New Testament Scriptures, and you will find that men objected to it in those days. When our Lord and Savior Jesus Christ spoke about it, He was always persecuted. People disliked Him for mentioning it. When He began to expose the depth of iniquity in the human heart and to talk about a rebirth, they invariably misunderstood Him. They disliked it then, and it has always been the same ever since.
…The natural man, the unregenerate human heart, objected to this great and wondrous biblical doctrine of rebirth and regeneration. And it is equally true today. People sit and listen to an address or sermon on what is called the fatherhood of God or the brotherhood of man and they never object to it. When they are exhorted to live a better life, they never express any objection at all. They say that it is perfectly right, and even though they are reprimanded for not living better lives, they say that it is perfectly true and quite fair and that they could do better. But if a preacher stands before the natural man and says, “You must be born again—you must have a new life from God,” they ask, “What is this strange doctrine?”
