According to a website which speaks about Calvinism v. Arminianism, one has aptly said: "The student seems to rightly recognize that inability alone cannot really decide the matter in favor of unconditional election since God could draw all to Himself (John 12:32), enabling all to believe and become the elect if that were how God sovereignly chose to do things (John 16:7-11; Titus 2:11; 1 Timothy 2:1-6;)."
This line of argument is true, if and only if it was the will of God to save all men and women. For the Supralapsarian the issue not whether God wanted to or did not want to save all people, but why He created the world. For one He did so to magnify His own glory by the salvation of electing some to eternal salvation and damnation of those who were reprobated to eternal damnation, and then He decreed to create both the elect and the reprobate and then decreed the fall of both the elect and the reprobate. So again the question is not about whether or not God COULD have elected all men the question is DID He? For one to answer this question he would have to go to Scripture and find out for himself.
