Man is tripartite being

Proverbs 23:7

“For as he thinketh in his heart, so is he…” KJV

Romans 12:2

“And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.” KJV

Man is tripartite being, he is a spirit, who has a soul and lives in a physical body. God is interested in all parts of our being. Some behave as though, it is only the spirit that God is interested in. In fact let us look at some
Scriptures to bring this home.

2 Corinthians 5:17

“Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.” KJV

1 Corinthians 6:17

“But the person who is united to the Lord becomes one spirit with Him.” AMP

1 Corinthians 6:19-20

“Do you not know that your body is the temple (the very sanctuary) of the Holy Spirit Who lives within you, Whom you have received [as a Gift] from God? You are not your own, You were bought with a price [purchased with a preciousness and paid for, made His own]. So then, honor God and bring glory to Him in your body.” AMP

1 Thessalonians 5:23

“And may the God of peace Himself sanctify you through and through [separate you from profane things, make you pure and wholly consecrated to God]; and may your spirit and soul and body be preserved sound and complete [and found] blameless at the coming of our Lord Jesus Christ (the Messiah).” AMP

When you were ransomed , you were ransomed spirit, soul and body. You are required to serve God with your spirit, soul and body.

Matthew 22:37

“And He replied to him, You shall love the Lord your God with all your heart and with all your soul and with all your mind (intellect).” AMP

I hope by now you can see clearly, that there is no part of you that is yours to use as you so desire, Jesus paid for you wholly, so give yourself wholly to God.
