'Impossible' in the Bible

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.
