That's not what Paul says. "Grace through faith."
Faith can be manipulated, subverted, redefined.
Grace cannot.
Do you believe there can be errors in some Christians' faith? I do.
Do you believe there are errors in God's grace? I don't.
You missed the point of what I said.
But you knew that.
Correct object, correct faith.
What are you trusting for salvation, the saving work of Christ is the correct object of faith.
Faith is not a sign of salvation, it is how one obtains salvation (Jn.1:12)
