I have not read this four page thread, so my comment is restricted to my understanding of 2 Peter 3:9.
(NASB) The Lord is not slow about His promise, as some count slowness, but is patient toward you, not wishing for any to perish but for all to come to repentance.
First the you refers to you born anew believers, but the issue is why is God being patient? Because our job as ambassadors of Christ is to carry out the ministry of reconciliation. Thus the "all" refers to all the lost, which we will reach more of because of God's patience. The claim that "all" refers to "all you Christians" is nonsense, we have already come to repentance. No, it is the lost that God is wishing that they would come to repentance.
