Romans 6:7...
"He that is DEAD, is freed from SIN"...
So If you are born again, then your old man, the carnal nature, the sin nature, is "crucified with Christ".= "reckon this OLD MAN dead to sin, but alive to Christ".
So, real Christianity is this........Ephesians 4:24.....>"""And that YOU put on the new man, which after God is created in righteousness and true holiness""
See that "new man"? That is the renewed mind that understands that this is the real you, and not the "dead man" that is "crucified with Christ".
So, when you are thinking about sinning, and worrying about confessing, then you are WEARING, .. you have put back on the "OLD MAN", IN YOUR FAITH.....that is the WRONG MIND......that is the "Mind of the FLESH" or the "natural mind"., and that mind is "enmity against God and cannot understand the Grace of God or the things of God as they are Spiritually Discerned" by the renewed mind, only.
SO, THAT IS a broken faith, or, its to have never yet understood that you are the new man, and you are to exist as "putting on the New man".
Thats REAL FAITH and that real faith allows GOD to empower you to live a perfected discipleship.
