I understand that. I do. We both agree that I can do nothing to assure my salvation. But is it so unlikely that I might want to say "Thankyou"? Am I adding to my salvation by thanking God for what Jesus did for me?
(I know you're not saying this, but please follow me.}
God provides the means by which God and I can be reconciled. And there is nothing that I can add or need to add in order to make that happen. But it is not adding to Christ's work for me to repent in response to that. My repentance isn't a necessary condition for my salvation. Rather, my repentance is an anticipated response to my reconciliation with God.
What I mean is this: while it’s true that God does everything and I add nothing to the *basis* of my reconciliation with Him, my repentance is the outward evidence that reconciliation has actually occurred. The apostles expect me to thank God for my salvation, not because gratitude contributes to it, but because gratitude expresses it. In the same way, they expect me to repent in light of what Christ accomplished on the cross. Repentance is not my contribution to salvation any more than thankfulness is — it is simply the external expression of an internal reality, the lived sign that I have embraced the reconciliation God has already provided.
Of course not, nor did I say anything otherwise. I believe just the opposite in fact - that we should profusely and continually thank God
for saving us - a gift that is far beyond our ability or comprehension or to remotely even understand what it means. However, should we believe that we contributed to it in any sense, then a part of the thanks would have to go to ourselves because of our contribution in addition to that of God's, which is an absurdity as there is only ONE (singular) Savior, Jesus Christ, not man.
