God taught this. In the words of Jesus himself
john 1: 12. but as many as have received him, to them he gave the right to become children, even to them who believe
john 3, for god so loved the world he gave his only son that whoever believes in him will never perish, but has eternal life, for the son was not sent to judge, but that the world might be saved, he who believes is not condemned, he who does not believe is condemned already
john 4: 13 Jesus answered and said to her, “whoever drinks of this water will thirst again, 14 but whoever drinks of the water that i shall give him will never thirst. but the water that i shall give him will become in him a fountain of water springing up into everlasting life”
john 5: 24 “most assuredly, i say to you, he whoever hears my word and believes in him who sent me who sent me has eternal life and shall not come into judgment but has passed from death to life
john 6: 35 and Jesus said to them, “i am the bread of life. he who comes to me shall never hunger and he who believes in me shall never thirst
john 6: 37: and the one who comes to me i will by no means cast out 38 for i have come down from heaven, not to do my own will, but the will of him who sent me. 39 this is the will of the father who sent me, that of all he has given me i shall lose nothing, but should raise it up on the last day. 40 and this is the will of him who sent me, that everyone who sees and believes in him may have everlasting life and i will raise him on the last day
john 6: 47 most assuredly, i say to you, he who believes in me has everlasting life. 48 i am the bread of life. 49 your fathers ate the manna in the wilderness, and are dead. 50 this is the bread which comes down from heaven, that that one may eat of it and not die 51 am the living bread which came down from heaven. if anyone eats this bread he will live forever
john 6: 63 it is the spirit who gives life ; the flesh profits nothing. the words that I speak to you are spirit and they are life
John 6: 54 Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. 55 For My flesh is food indeed, and My blood is drink indeed. 56 He who eats My flesh and drinks My blood abides in Me, and I in him. 57 As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me. 58 This is the bread which came down from heaven—not as your fathers ate the manna, and are dead. He who eats this bread will live forever.”
so what Did Jesus say is required
1. We recieve him
2. We believe in him
3. We drink the water of life he is offering us
4. Hears the word and believes
5. We come to him
6. We see and believe
7. Eat his flesh and blood
8. We feed on him.
what does all this mean?
It is the spirit who gives life. the words he speaks is spirit and life.
we are washed by the washing of water by the word.
But God will not force us to recieve this gift. We must in humility recieve it
Every passage you quoted actually proves the opposite of what you are trying to argue, because Jesus never presents salvation as a
human‑initiated reception but as a
Spirit‑given response to His own life‑giving words.
When Jesus says “receive,” “believe,” “come,” “drink,” “eat,” and “hear,”
He immediately explains that
the Spirit gives life and the flesh profits nothing, meaning these actions are not human prerequisites but Spirit‑enabled responses flowing from the life He gives.
John 6 makes this explicit:
“All that the Father gives Me will come to Me… and I will lose nothing but raise it up on the last day.”
That is not an offer; that is a guarantee.
The same chapter says no one can come unless the Father draws, and everyone drawn is raised — which means salvation is not a marketplace where God waits for humility, but a miracle where God gives life to the dead.
Your list of “requirements” collapses under Jesus’ own explanation: believing is Spirit‑given, coming is Spirit‑drawn, drinking is Spirit‑enabled, eating is Spirit‑sustained, and eternal life is Spirit‑secured.
The entire point of John’s Gospel is that
eternal life is the result of Christ’s action, not the condition of ours, and every promise Jesus makes — “never perish,” “never thirst,” “never hunger,” “never cast out,” “lose nothing,” “raise on the last day,” “live forever” — is unconditional because the Spirit produces the very faith He commands.
your argument assumes human autonomy; Jesus teaches divine initiative. That’s the difference, and that’s why OSAS is simply taking Jesus at His word. I'm not denying your diligence, and even I struggled with this at first. But we can walk through it more if you need to.
