The seeming disjunction centers upon distinguishing between soul and spirit. Before being born again the spirit is sequestered in/with the soul, the behavior mechanism. Once one is born again, born from above, God has separated the soul and spirit so that His Spirit can abide in the newborn spirit in the righteousness of Christ. The flesh continues to sin, hopefully less and less as the Christian matures, but the spirit which God has separated from the flesh has The Spirit of God abiding therein and cannot sin because the seed of GOD is abiding therein and God cannot sin or hold His Presence among sin. And God is not a yoyo that comes and goes and comes again into the spirit. Cults focus upon the soul not the spirit. Seven_0 is not a cultist.
MATTHEW 26:41 KJV
“Watch and pray, that ye enter not into temptation;
the spirit is willing, but the flesh is weak.”
