Nah you just misunderstood the question
My point is this. The power is not in our faith. The power is in the one we believe
Setting aside regen for a moment. Jesus said “ if you have faith as a grain of mustard seed, you can say to this mountain be moved and it will be moved. Is it your faith that moves mountains or God? It is God. faith is necessary, but of God is the power and to Him is the Glory
In the same way, if we have faith, which is itself a gift of God, we will be raised to new life. Faith is necessary. Without it, we are lost, and it is the only thing we have to bring, (but remember it is a gift of God), but in salvation, His is the power and to Him goes all the Glory
