Then the LORD said to Moses, "Make a fiery serpent and mount it on a pole. When anyone who is bitten looks at it, he will live." So Moses made a bronze snake and mounted it on a pole. If anyone who was bitten looked at the bronze snake, he would live. (Numbers 21:8-9 BSB)
Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else. (Isaiah 45:22 KJV)
Just as Moses lifted up the snake in the wilderness, so the Son of Man must be lifted up, that everyone who believes in Him may have eternal life. (John 3:14-15 BSB)

Look and be saved! Salvation is that simple. But do not let what is good become an idol. Neither should we add to the method of salvation. Just look. That is all.

He removed the pagan shrines, smashed the sacred pillars, and cut down the Asherah poles. He broke up the bronze serpent that Moses had made, because the people of Israel had been offering sacrifices to it. The bronze serpent was called Nehushtan. (2 Kings 18:4 NLT)
For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. (John 3:16 KJV)
