“I have some immediate questions: One question that I have right off the bat is about the word “believe” in 3:16. Perhaps Jimmy could help shed some light here. Does it mean that I believe that Jesus is the son of God? So does Lucifer, shall he have eternal life?”
While I am sure Jimmy could shed A LOT of light on this subject, I think I have the answer and I shared it in the previous post. The key to understanding John 3:16 is in John 3:13-15. It refers to the story in Numbers 21:4-9.
4 Then they set out from Mount Hor by the way of the Red Sea, to go around the land of Edom; and the people became impatient because of the journey.
5 The people spoke against God and Moses, "Why have you brought us up out of Egypt to die in the wilderness? For there is no food and no water, and we loathe this miserable food."
6 The LORD sent fiery serpents among the people and they bit the people, so that many people of Israel died.
7 So the people came to Moses and said, "We have sinned, because we have spoken against the LORD and you; intercede with the LORD, that He may remove the serpents from us." And Moses interceded for the people.
8 Then the LORD said to Moses, "Make a fiery serpent, and set it on a standard; and it shall come about, that everyone who is bitten, when he looks at it, he will live."
9 And Moses made a bronze serpent and set it on the standard; and it came about, that if a serpent bit any man, when he looked to the bronze serpent, he lived.
Numbers 21:4-9 NASB
First off Luke, I was wrong about something. I thought that the story about Israelites being bitten by snakes only made them wish they would die. I was wrong the snakes were killing the Israelites. This is what happens when you reiterate a story by memory and don’t check the source. When they complained to Moses asking Him to intercede with Jehovah to get Him to take the snakes away, Jehovah had Moses do something unexpected. He had Him make a likeness of the snake and lift it up in the wilderness. Then He instructed the people who had been bitten to look upon the snake and they would be healed and not die. There was no merited favor, no works that needed to be done, simply having enough faith to look at the snake to be healed. Simple faith that Jehovah would do what he said He would do.
It is interesting to note that Jehovah did not do what the Israelites wanted Him to do. The most logical thing in their minds was to have G_d get rid of the snakes. Instead He forced them to believe in faith that he would not let them die even if they were bit by one of these deadly snakes. They would still suffer the consequences of their rebellion (being bit by the snakes) but they would not die if they had faith to look upon the image of the snake to be healed.
Yeshua was pointing out that the kind of faith and belief in Him, the Son of Man, is the same kind of faith and belief the Israelites had to exhibit in looking upon the serpent to be healed from the bite of the snake. If we have the belief in faith that He will do what He said He would do then He will be just and faithful and forgive us of our sins. The Word does make reference the demons believing and trembling but not having faith. So the key is faith, not believing that He is the Son of G_d, but believing IN Him and what He did for us. Faith pure and simple nothing more nothing less.
