'Possible' in the Bible

And Jesus looking upon them'said to them, With men this is impossible; but with God all things are possible.

For there shall arise false Christs, and false prophets, and shall show great signs and wonders; so as to lead astray, if possible, even the elect.

And he went forward a little, and fell on his face, and prayed, saying, My Father, if it be possible, let this cup pass away from me: nevertheless, not as I will, but as thou wilt.
