'It is I' in the Bible

And Jesus, having looked upon them, saith, 'With men it is impossible, but not with God; for all things are possible with God.'

And he said unto the disciples, 'It is impossible for the stumbling blocks not to come, but woe to him through whom they come;

for the fruit of the Spirit is in all goodness, and righteousness, and truth,

for it is impossible for those once enlightened, having tasted also of the heavenly gift, and partakers having became of the Holy Spirit,

that through two immutable things, in which it is impossible for God to lie, a strong comfort we may have who did flee for refuge to lay hold on the hope set before us,

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

and apart from faith it is impossible to please well, for it behoveth him who is coming to God to believe that He is, and to those seeking Him He becometh a rewarder.
