In order to understand the importance and impact of the blood of Christ shed for mankind at His crucifixion, we must view man according to God’s intention, when man was created. Man was created with the intention of becoming a living human container who would ultimately come to bear the very life of God – man would become a living vessel suitable for God’s free expression through man. Man then would recover, reign and bless the earth as God’s representative.

For this, man was created tri-part, with a body, soul, and human spirit. God’s intention was that one day God would place His very “spirit of life” into the created man’s human spirit, thus making the created man to be reborn in spirit – to be born of the very life of God Himself. God’s life and nature received into the man’s human spirit would become expressed via man’s soul faculties of mind, emotion, and will. This intention of God for man is first indicated in the Bible by the fact that God placed Adam and Eve before the Tree of Life – the tree as a figure of Christ as the bearer of the life of God to man (See John 15).

This verse lists the three parts of man in their proper order of authority. 1 Thes. 5:23 And the very God of peace sanctify you wholly (completely); and I pray God your whole SPIRIT AND SOUL AND BODY…

From Inside Out:

We should note from this verse, by a hermeneutic device called “the law of first mentioning,” that the “spirit” is listed first, placing it as the foremost part of man’s being. God intends that the life in the spirit is to rule the faculties of the soul organ, and soul is to rule the doings of the body. Thus, when religion tells us we need to try to outwardly “do things” or “act in a certain way” in order to prove our being a Christian they miss the focus of God’s plan that Christ articulated to Paul for we Gentiles. That plan was that God’s life would indwell the human spirit of every person who receives Christ’s Spirit, automatically producing the fruits of that life.

This then brings us to see the physical body as the least part of man’s according to God’s eternal plan. Man’s body is to be the servant of man’s spirit-life. It is in the members of the physical flesh body that Sin as a nature dwells (Rom 7:17-23), needing to be ruled over by Christ from within the believer’s spirit. The body contains the fallen nature that Adam gained at the fall in the garden, and which came also to all mankind as being of the lineage of Adam (Rom 5:12). Rom 8:3 …God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: Here we see exactly where Sin as a nature is rooted in mankind – in his flesh body.

The Sin nature in man’s flesh has now fully contaminated the originally created man, including his soul/mind, producing the “acts of that Sin nature in His flesh,” which we call sins. Now, Romans 8:7 (Darby) Because the mind of the flesh is enmity against God: for it is not subject to the law of God; for neither indeed can it be:

The created man, created to be a living vessel for God’s expression, has become a dirtied potential container of the life of God; dirtied by acts of Sin in the flesh. God planned to gain “many sons” by placing the life-seed of His only begotten Son, Jesus Christ, into men. But, if God is to bring the fallen created man into accord with His eternal plan, there is a problem that first needs to be remedied – its man’s sins.

God told Israel, via Isaiah, your sins have separated you from God. Isaiah 59:2 But your iniquities (sins) have separated between you and your God, and your sins have hid his face from you, that he will not hear. Paul here speaks of the former condition Gentiles who have become believers. Ephesians 2:1 And you hath he quickened (made alive), who were dead in trespasses and sins;

God’s remedy to cleanse man of his sins is the precious royal blood that was shed one time by Christ at the cross; to remit, cancel, and take away all sins of those who would simply have faith to trust in His shed blood.

Colossians 1:14 In whom we have redemption through his blood, even the forgiveness of sins.

Romans 3:24-25 (NASB) BEING JUSTIFIED as a GIFT BY HIS GRACE through the redemption which is IN CHRIST JESUS; ²⁵ whom God displayed publicly as propitiation (as the atoning sacrifice witnessed) IN HIS BLOOD THROUGH FAITH…
