Who could have imagined that the circumstances surrounding the serpents described by Numbers Chapter 21, would be a representation of what Jesus would accomplish for us at the Cross? Those bitten by these “fiery serpents” were able to prevent their death by simply lifting up their eyes to look at the serpent on the pole which Moses had made.
Numbers 21:9 So Moses made a bronze serpent, and put it on a pole; and so it was, if a serpent had bitten anyone, when he looked at the bronze serpent, he lived.
 Jesus later described this event in the desert as a foreshadow of the time when He would also be “lifted up” on the cross–so that anyone who would look to Him for their salvation–would also be saved.

John 12:32 “And I, if I am lifted up from the earth, will draw all peoples to Myself.” (more…)
