"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."

"...whosoever believeth..."

That says nothing about Nag Hammadi or reading a book by Allegro or anyone else. Putting foolish conditions like that on God's perfect plan for salvation is fake news.

Jesus said, "I am the way, the truth, and the life: no man cometh unto the Father, but by me."
