That God will write His law, His commands on our hearts. God is the one who performs this process not us, love is written into our hearts and love fulfills everything the law ever required.
Jesus did not suffer and die so that we do not covet thy neighbors oxen. Jesus died to generate a new creation, a creation overflowing with faith and love.
The letter of the law kills, your flesh as been crucified with Christ, you are baptized into death. You are already dead in your sin but Christ is the one who resurrects you in the Spirit.
We walk by the Spirit and not by the flesh, we are a new creation in Christ. Fully reconciled in Jesus, free from that law of sin and death.
Seated with Christ in the heavenly realms. We are not striving to be holy people, we are all holy people in Jesus Christ. Our holiness, our righteousness is given to us a free gift in Jesus Christ.
Either accept the free gift in Jesus Christ and live the life of liberty in the joy of the Holy Spirit. Or exert your own holiness and claim that you are a Christian. The choice is yours.
