'It is I' in the Bible

For it is impossible, in the case of those who have once for all been enlightened, and have tasted the sweetness of the heavenly gift, and have been made partakers of the Holy Spirit,

it is impossible, I say, to keep bringing them back to a new repentance, for, to their own undoing, they are repeatedly crucifying the Son of God afresh and exposing Him to open shame.

He added an oath, in order that, through two unchangeable things, in which it is impossible for Him to prove false, we may possess mighty encouragement--we who, for safety, have hastened to lay hold of the hope set before us.

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

But where there is no faith it is impossible truly to please Him; for the man who draws near to God must believe that there is a God and that He proves Himself a rewarder of those who earnestly try to find Him.
