First, it should be clearly stated that in human nature, there is a “bent,” or desire to sin. Therefore, you would be more accurate in describing the Evangelical thought regarding this topic as human nature being corrupt. It will surely draw towards that which will gratify itself, resulting in sin. Again, this is why the apostle stated, “For I know that nothing good dwells in me, that is, in my flesh.” What we find is that it is Roman Catholic theology that declares that human nature is good, and this is where we have come to a wall; hence, there would not be the necessity of the new birth.
The problem that we have run into is comparing the Lord Jesus Christ to fallen man—fallen in the sense that we all have sinned are by nature children of wrath. Yes, I wholeheartedly acknowledged Christ as human; but it must be equally understood that He was completely divine as well. Jesus was the “unique” son of God, therefore we must identify His nature in this totality. His seed did not come from Adam, but it was the Holy Spirit who overshadowed Mary, in which a divine seed was placed. Therefore, He was not completely like us. Yes, He was human; but He was equally God as well—and this cannot be ignored or overlooked. Jesus never sinned because, as He stated, “The Son can do nothing of Himself, unless it is something He sees the Father doing.” This being so, it should not be difficult to understand why Jesus never sinned.
Again, the scriptures—from Jesus, to Paul, to Peter, to John—decisively declare the need and blessing of being born again. Remember the statement that John said, in which I quoted for you on two different occasions, “Whosoever is born of God cannot sin because His seed remains in him.” Hence, the scriptures posit the necessity of the new birth because it is the implantation of a divine life within the heart of a believer. Without this divine life, man is still corrupt and dead in his sins.
Thank you for the dialogue, and I am sure that our paths will cross again should the Lord tarry.
