'Impossible' in the Bible

"Because your faith is so small," He replied; "for I solemnly declare to you that if you have faith like a mustard-seed, you shall say to this mountain, 'Remove from this place to that,' and it will remove; and nothing shall be impossible to you.

Jesus looked at them and said, "With men this is impossible, but with God everything is possible."

Again a second time He went away and prayed, saying, "My Father, if it is impossible for this cup to pass without my drinking it, Thy will be done."
