Due to the sins of the people Israel, many were being bitten by serpents and dying. When they repented and asked for God's healing, the Lord instructed Moses to make a bronze serpent and mount it on a pole. In order to be healed, they had to look upon the bronze serpent (with faith that God could and would heal them). This bronze serpent
prefigured Jesus Christ lifted up upon the cross. We need God's healing. With faith in Christ Crucified and trust that He has the power and the will to heal us, we will receive healing, that we not experience eternal death, but eternal life surrounded by the love of God.
