What does a snake have to do with salvation?

John 3:14-16 (King James Version)
And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up: That whosoever believes in him should not perish, but have eternal life. For God so loved the world, that he gave his only begotten Son, that whosoever believes in him should not perish, but have everlasting life.

Numbers 21:5-9 (King James Version)
And the people spake against God, and against Moses, Wherefore have ye brought us up out of Egypt to die in the wilderness? for there is no bread, neither is there any water; and our soul loathes this light bread. And the Lord sent fiery serpents among the people, and they bit the people; and much people of Israel died. Therefore the people came to Moses, and said, We have sinned, for we have spoken against the Lord, and against thee; pray unto the Lord, that he take away the serpents from us. And Moses prayed for the people. And the Lord said unto Moses, Make thee a fiery serpent, and set it upon a pole: and it shall come to pass, that every one that is bitten, when he looks upon it, shall live. And Moses made a serpent of brass, and put it upon a pole, and it came to pass, that if a serpent had bitten any man, when he beheld the serpent of brass, he lived.

Yeshua (Jesus) literally means salvation in Hebrew.

He is your ticket to freedom, peace and bypassing the final judgment. Will you accept the simple good news gospel gift? This gospel proclaims Jesus' death on the cross is payment in FULL for the sin of those who believe in him and his resurrection from the dead. This is proof of your justification and confidence in His power. This is where faith comes in. If you can believe this simple message and declare by faith that Jesus is LORD, thereby yielding your life to his will and not your own, you WILL be saved. Be sure to join a bible living church, read your bible and talk to your heavenly father every day and never trust in your goodness for your standing with God, but instead trust in His goodness, because he loved you and took your punishment for you so that you could go free as a good good father would do! He gave ALL he could give so NOW, its up to you! What will you do?
