How do we know that looking at the bronze serpent was significant for salvation?

The command to look at the bronze serpent served as a test of faith for the Israelites. Despite the absurdity of the remedy, it required trust in God’s word. This parallels the New Testament teaching that believing in Christ, who was lifted up on the cross, brings eternal life. Just as the Israelites were saved by physically looking at the serpent, believers today are saved by looking to Jesus in faith, acknowledging His sacrifice for our sins. This narrative underscores the important truth that salvation is not by works but by faith in what God provides.
