What does the brazen serpent symbolize in the Bible?

The brazen serpent, as described in Numbers 21:8-9, serves as a powerful symbol of Christ's sacrifice. In John 3:14-15, Jesus Himself draws this parallel, indicating that just as the serpent was lifted up for the healing of the Israelites, He would be lifted up on the cross for the salvation of humanity. This typology illustrates that faith in Christ, who bore our sins, is necessary for spiritual healing and eternal life. It underscores the biblical theme of redemption through God's provision for sinners, demonstrating that we must look to Christ in faith for deliverance from sin and death.
