What does the Bible say about salvation through looking to Christ?

In Numbers 21:8, God instructed Moses to make a fiery serpent and set it upon a pole, stating that anyone who looked at it would live. This acted as a foreshadowing of Christ, who would be lifted up on the cross. Just as the Israelites needed to look to the serpent to be saved from the venomous bites, we must look to Christ for our spiritual salvation. Isaiah 45:22 emphasizes this concept by calling all the ends of the earth to look to God for salvation, reinforcing that our faith must rest solely in Him.
