What is going on in the desert when the bronze serpent is lifted up as a healing remedy to the Israelites? (Numbers 21) Diving into the Old Testament will give us greater perspective by which we can understand Jesus allusion to his own "lifting up".

What is clear? The wages of sin is death, and idolatry is the origin of it. Jesus' blood is the anti-venom capable of healing us from the poison of the worship of Satan, the serpent, whose lies tempt us to doubt and deny God's goodness and provident love for his people.
