I must admit that I certainly didn't expect to hear YOU say THAT!!
What do you mean by it????
I heard an excellent Reformed sermon on Isa 63 so it's not my material. God considered Himself the Savior of these unbelievers, but from these people perspective they wanted nothing to do with God. I think that is exactly what John and Peter are talking about. Our Lord Jesus blood does not atone for them nor does it cover their sins. Yet God, like the unbelieving Israelites, considers them His Savior.
I will say this is rather bizarre (did I spell it right P-M?). What is even more strange is that God deliberately harden their hearts and caused them to err. Nevertheless there it is and I think it is consistent the what John and Peter states.
1) God considers Himself to be Savior of mankind.
2) Man doesn't want a Savior. Man rebels against God as Savior and vex His Spirit.
3) God's wrath rests on man.
4) God hardens man and cause him to err for His divine cause.
5) God purposely saves a remnant to be a people holy to Him for His glory.
6) Those who are save are covered because of our Lord Jesus' atonement.
7) God initiates all steps. Without His intervention all would be lost.
