“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life”.
That verse is the foundation supporting every Christians’ faith. Christians when challenged about their beliefs will always come back to this “I can’t explain why WHATEVER but I know that Jesus died on the cross for me.”
Christians believe John 3:16 is literally true but will reject other nonsense in the Bible as being “not literal, taken out of context, not for us to know, etc. etc. etc.” So, let’s take a look at other verses in John that Christians, to avoid being charged with hypocrisy, also have to believe to be the literal truth.
“And he saith unto him, Verily, verily, I say unto you, Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of man”
Jesus falsely prophesied that Nathaniel would see heaven open and angels descend upon Jesus. Nathaniel never saw it; neither has anyone else.
He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
Jesus believed in the snake-on-a-pole story of Numbers 21, God’s 23rd Killing. He believed that God sent fiery serpents to bite and kill the people for complaining about the lack of food and water. And he believed that God told Moses to make a brass serpent and put it on a pole so that those who looked at it would be magically cured. And he was OK with all that.
You have to be OK with that too, right? In fact, Jesus said his own death would be just like that. If you believe in Jesus’ magical death, you’ll be saved just like the people that had been bitten by God’s fiery serpents were saved by looking at Moses’ magic snake on a pole
