'It is I' in the Bible

and having fallen away, it is impossible again to renew to a change of mind, they having crucified again and exposed to shame the Son of God.

that by two immutable things, in which it is impossible for God to lie, we might have strong consolation, who fled to lay hold on the hope set before us,

for it is impossible that the blood of bulls and goats should take away sins.

but without faith it is impossible to please; for he that comes to God, must believe that he is and that he is a rewarder of those that seek him.
