1Th 5:23 And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ.
Many miss the boat on this because they forget that man is created in the image of God.
God is tripartate- Father son and Holy Spirit.
Man is tripartate- spirit, soul (mind ,will,intellect, emotions,etc) and body
When we are born again we recieve an New Spiritual life and instantly become a new creature in Christ. This new man is created in God's image and does not sin.
Now we have to be renewed in our minds by the Spirit and the Word.
Our bodies will follow our thoughts in every area wether our minds are renewed in that area or not.
Your spirit receives revelation from God and your soul gladly recieves that revelation- you began to think in aggreement with God in that area and your body goes where your mind tells it. You are renewed in that area and walk according to His Word and will.
But take another area where you are unrenewed- all you old thinking is quite anti-christ. Even the more noble thoughts and actions are corrupt to the core as the old man has his own motivations, desires his own will and seeks glory for himeself (love, recognition etc). The deeds of the flesh can never be acceptable in His sight.
God has called us into death to self- pick up the cross daily- die to the old - each time you die to the old you will find His ressurection power giving life.
Rom 7:18 For 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.
