The word sin in the Greek is hamartia a noun-which means to be without a share in. the root of the word consists of two words ( a- without and meros meaning a part due or assigned to one, a lot, inheritance or destiny).
So sin means not a part of or not having a share in. The definite article is used a lot in the New Testament referring to “the sin”. The lostness of our identity we inherited from Adam.
So sin is a spiritual state in which we are not partaking of the divine nature which leaves an emptiness in which other things enter into our heart in which we try to get our God given needs met. This is why the word sin is often personified referring to demons.
Sin is the loss of our inheritance from God, our identity, and our destiny, which is restored in a face to face relationship with God our Father, through the cross of Jesus Christ. In Adam all die, in Christ all are made alive.
Sin is the loss of our shared image as sons of God. It is a noun and not a verb. It is a nature and not an action.
Trespasses are an action. The cross deals with sin and the blood deals with trespasses.
When we were born a human being, we were in Adam and inherited a fallen nature, a sin nature.
Jesus was the last Adam. When He died on the cross, the whole human race in Adam died with Him.
Our sin nature, the old nature was crucified with Christ. The cross deals with sin.
When Jesus was raised from the dead, He became the second man, the first born from the dead. The first born of a whole new species of beings, called the new creation.
If any person be in Christ, they are a new creation. When Jesus was raised from the dead, we were raised with Him, and seated with Him in the heavenly places in Christ.
The reason people struggle with sin is because they do not have a revelation of what it means to be in Christ, to be a new creation.
They may believe they are a new creation in their mind, but the word has not been engrafted into their spirit.
God has to reveal this to our spirit, our spirit needs this revelation. The light of God has to shine in our spirit so that our spirit comes alive to this truth, so that we are able to join our spirit to the Lord, as one spirit in Christ.
When this happens, the grace of God is given us to overcome sin. The life of God flows into our spirit empowering it to take the ascendency in our life, where our soul and body come under subjection to the Lord ship of Jesus over our spirit.
Then we ascend into the heavenly places in Christ, into the realm of the Kingdom of God, and the gravitational pull of the world no longer has a hold on us and we become more than a conqueror.
This is an experience called Sanctification, where we walk in the Spirit and no longer fulfill the lust of the flesh.
