'It is I' in the Bible

But Jesus straightway spake to them, saying, "Be of good cheer. It is I; be not afraid."

for they all saw Him; and were troubled. But he straight-way talked with them, and saith to them, "Be of good courage! it is I, be not afraid."

Jesus, looking upon them, saith, "With men it is impossible, but not with God: for all things are possible with God."

And He said to His disciples, "It is impossible but that occasions of stumbling should come; but woe to him through whom they come!

See My hands and My feet, that it is I Myself; handle Me, and see; because a spirit does not have flesh and bones, as ye behold Me having."

But He saith to them, "It is I; be not afraid."

which is present among you, even as it is in all the world bearing fruit and increasing, as it does in you also, since the day ye heard and knew the grace of God in truth;

and then fell away, it is impossible to renew them again to repentance, since they are crucifying to themselves the Son of God afresh, and putting Him to open shame.

that, through two immutable facts, in which it is impossible that God should lie, we may have strong encouragement, who fled for refuge to lay hold of the hope set before us;

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

And, apart from faith, it is impossible to please Him; for he that comes to God must believe that He is, and that He becomes a rewarder to those who seek after Him.

What profit is it, my brethren, if anyone says he has faith, but has not works; can such faith save him?

and every spirit that confesses not Jesus is not of God; and this is the spirit of the Anti-Christ, of which ye have heard that it is coming, and now it is in the world already.
