All this is from God… ESVUK

As God’s sovereignty is seen in creation, so it is with the new creation. We do not save ourselves. We cannot reconcile ourselves to God. This is a humbling truth, but one to be received with great gratitude.

 “We do not cause the new birth. God causes the new birth. Any good thing that we do is a result of the new birth, not a cause of the new birth. This means that the new birth is taken out of our hands. It is not in our control. And so it confronts us with our helplessness and our absolute dependence on someone (namely, God) outside ourselves.” John Piper
