Well, HP, that is certainly not an attitude I would recognize in other Christians! We sin. That is that. Our hearts are changed when we are born again. Before, we are the same as God told Noah -- with our hearts always INCLINED toward evil. We can resist that inclination even as unregenerate people -- that is what general morality, ethics, and laws are all about. When we are born again, our hearts are changed and we no longer WANT to sin, but the simple truth is, we do, as long as we are in these earthly bodies. That is why John told us that if anyone says he does not sin the truth is not in him. But if we confess our sins, our Lord is faithful to forgive us.
It is the inclination of the heart that is the first change when we are born again. After that, the Holy Spirit works within each of us (Romans 8:9) to change us into the image of Christ (Romans 8:28-30), and He is faithful to complete the good work He has begun in us (Philippians 1:6). Something that is started and still must be completed is a process. I am in process of being formed into the image of my Lord and Savior, Jesus Christ. I am not there yet, but neither am I evil.
The soul and the spirit are separate, but that is not the point of this thread, is it? If it is, then I missed it entirely.
