Benjamin,
I really thought I read that you made much of disagreeing over "proof-text" methods that would attempt to support a view.
But, did you not do that in this post?
Example: You stated a portion of John 1, but you applied it inaccurately to include all humankind having some ability.
Such is NOT given in this passage, in fact John is VERY sensitive to express EXACTLY the point that God is totally in charge and NO humankind has ANY involvement in the process of selection or salvation.
Here is the whole section with bold that DISCREDITS your proof-text post.
6 There came a man sent from God, whose name was John. 7 He came as a witness, to testify about the Light, so that all might believe through him. 8 He was not the Light, but he came to testify about the Light.
9 There was the true Light which, coming into the world, enlightens every man. 10 He was in the world, and the world was made through Him, and the world did not know Him. 11 He came to His own, and those who were His own did not receive Him. 12 But as many as received Him, to them He gave the right to become children of God, even to those who believe in His name, 13 who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
I won't take the time to explain that the light (vs 7,9) that lightens EVERY man is the ten commandments (see the use of past tense - was), nor do I need to explain the word "might" in "all might be saved" (vs 7)is referring to the hope of John and not to be applied to the hope or desire of Christ.
Benjamin, I don't really understand how someone can miss understand that opening of John.
May I suggest that often a view is made askew which results in bias that further distorts the view. As is in cases such as this, the view clings to a portion to the point of dismissing what may be a clarification of that portion.
What John states (last bold part) clarifies ALL the "ALL" words before and just how receives and who is saved.
If John had not included that portion, then you might have some slim ledge in which to build upon, but there is no such support - so your argument fails.
But at least you did post a few verses in attempts of supporting your post.
That in itself is an improvement. I really hope you will continue in this mode of supporting by Scriptures the principles you view as essential.
