1 Corinthians 2: 14But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. The natural man, as in the flesh cannot receive the things of God it is bound to death. God through the words of Jesus can go past this flesh and go right to the inner man can bring salvation to the soul. God is not saving the natural man, nor does God need to save His Spirit, because why would God have to save Himself. He is saving our soul Your soul is given a choice to follow the flesh that leads to death, or to follow the Spirit that leads to life. Matthew 10:28 Do not be afraid of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in hell. John 6:63 The Spirit gives life; the flesh counts for nothing. The words I have spoken to you are spirit and they are life. Romans 7:18For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. 1 Peter 1:9 for you are receiving the goal of your faith, the salvation of your souls.
