Galatians 5:16 But I say, walk by the Spirit and you will not carry out the desire of the flesh.
We are made in the likeness of God, that is, three in one. We are spirit, soul (mind) and body.
We were born under the curse of the law because of the fall of man through Adam. Our spirit man, soul and body were subject to trying to earn our salvation by following the law, which we could not do, eventually leading to death.
Through Christ and the grace He provided through His perfect life, death and resurrection, we were made new creatures in Him. Our old sinful spirit man was crucified and buried with Christ. He took our sins and nailed them to His cross.
We now have a new righteous spirit man within us. We still have a soul (mind) that needs renewed and an earthly body that will one day be changed into a spiritual body, but for now, God sees us as the righteousness of Christ, who lives within us by His Spirit.
Naturally speaking we will never be perfect on this earth, but because of the grace of Christ, God sees us spiritually as perfect already.
This doesn’t give us permission to live as we want and do whatever, but now we live for God and do what pleases Him out of love and not out of obligation. We now take up our cross daily and follow Him, allowing Him to increase as we decrease.
When you make a mistake, it is covered. We don’t have to repent each time, but we do acknowledge we made a mistake and thank God for His Grace that covers it.
A good thing to confess out loud after allowing our mind or body to take control is ‘I am the righteousness of God’. This will help us to remember God’s gift of grace and get us focused on our spiritual position in Christ.
