After man sinned in the garden, it has become part of us to have a sinful nature. So it's just like an Adamic nature in us that we have inherited. Then God created us. We are wonderful and beautifully made, but since man did not obey the instruction of God, sin became part of us. They were meant to deceive us and everything.
The Lord Jesus Christ is telling us that. He has died for us to wash away our sins and redeem us from evil by sacrificing himself. So that cross was the beginning of our new life. He died for us so that we can live a righteous and holy life and God can have mercy on us.
This will of God is never in our position. Sometimes our flesh works according to our will, our spirit. We want to do good but our flesh is not allowing us to do good. To be able to do what is right, we must try our best to not allow the flesh to get hold of us. We must obey the word of God. We must submit to ourselves.
The Holy Spirit should be able to guide us into obeying the instruction of God. That is how we should live our life as a Christian and do the will of God.
