'It is I' in the Bible

For it is impossible to renew to repentance those who were once enlightened, who tasted the heavenly gift, became companions with the Holy Spirit,

so that through two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to seize the hope set before us.

For it is impossible for the blood of bulls and goats to take away sins.

Now without faith it is impossible to please God, for the one who draws near to Him must believe that He exists and rewards those who seek Him.
