What does the Bible say about looking to Jesus for salvation?

In John 3:14-15, Jesus draws a parallel between the serpent lifted by Moses in the wilderness and His own impending crucifixion. He explains that just as those bitten by the fiery serpents needed only to look at the bronze serpent to live, those who believe in Him will have eternal life. This highlights the importance of faith and looking to Christ, who was lifted on the cross to take upon Himself the curse of sin. The act of looking signifies faith, acknowledging that salvation comes solely through Him, not through any works or efforts of our own.
