'It is I' in the Bible

But Jesus immediately spoke to them, saying, Be of good courage; it is I; be not afraid.

for they all saw and were troubled. And immediately he spoke with them, and said to them, Be of good courage; it is I; be not afraid.

Jesus looking on them, said, With men it is impossible, but not with God; for with God all things are possible.

AND he said to his disciples, It is inevitable that offenses should come; but woe to him by whom they come;

But he said to them, It is I; be not afraid.

Whether therefore it is I or they, so we preach, and so you believed.

Have you suffered so much in vain? if indeed also it is in vain.

For this cause also we thank God without ceasing, that receiving the word of God heard from us, you received not a word of men, but, as it is in truth, a word of God, who also works in you that believe.

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.
