There is no condition. It's "everyone who IS BELIEVEING".LOL
Ignore not ignorant
You are not reading well and you ignored this
John 3:14-15 (KJV)
14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:
15 That whosoever believeth in him should not perish, but have eternal life.
there are still two conditions in that passage
Can you be saved without Christ's sacrifice?
Can you be saved without faith?
those are conditions it is irrelevant who fills those conditions
they must be fulfilled
Sorry the idea that faith merit salvation is not a biblical one
and the ideas that it is man who believes is also a biblical one
Speaking of ignoring.
