The Unlimited Atonement Implies Unlimited Opportunity For Salvation

I John 4:14-15 reads "... the Father sent the Son to be the Saviour of the world. Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God."Do you see how the fact that anybody and everybody who wants to be saved can, is tied to the fact that Jesus died for all (and not just the elect)?John 6:51 teaches the same as it reads "... and the bread that I (Jesus) will give is my flesh, which I will give for the life of the world . if any man eat of this bread, he shall live for ever"Jesus died for everybody so that whosoever chooses to serve God (Joshua 24:15) can be saved.So it is true that if you disprove one point of Calvinism, then the whole system falls !
