Presalvation repentance? No.
Postsalvation repentance? Yes,..namely the sin unto death if the believer out of fellowship continues down a path such that all opportunities for God the Holy Spirit to perform a good work in us are all burnt up, so to speak.
Since God does nothing that is good for nothingness, He will not continue to indwell us, if all instances in His Plan have been denied to the point where we are no longer effectual and refuse to return to Him.
It is also possible for believers to fall out of fellowship, remain saved, but fail to walk the walk. Divine discipline manifests He still loves us in these situations. Not all adversity is from His discipline, but some discipline is rendered to get our attention for us to return to Him.
A good example is Paul and his many stays in prison when Paul attempted to return to Jerusalem to teach the Pharisees and Jews, when in God's Plan, Paul was to be an Apostle to the Gentiles and go to Rome.
Ok.. I find your theology a bit complicated.. sorry :)
But.. would I be correct in saying you do not belong to those who believe Once Saved Always Saved?
I have to clarify this part though:
>>”Postsalvation repentance? Yes”
One can enter Heaven with sins they do not repent of? Is there a limit here, either qualitative or quantitative?
