==I don't know a Calvinist, including myself, who would say that man does not have a choice. Man does have a choice. However, and this is the big problem, man will always choose to go against God (Rom 3:10-12). Man's "free-will" or "choice" always leads him to make the wrong choice. Why? Because lost man is dead in sin, in slavery to sin, and in love with the world. They are enemies of Holy God, children of wrath, and can do nothing to please Him. The only way a person can chose to come to Christ, can chose to believe, is for God to bring that person to a point of saving faith.
==Jesus said that all the Father has given Him will come to Him and will recieve eternal life (Jn 6:37, 17:2) and will finally be with Him where He is (Jn 17:24). Jesus also said that the one who comes to Him will not be cast away (Jn 6:37). That has a two fold meaning:
1. They will not be turned away. Nobody whom the Father has given to the Son and drawn to the Son will be turned away by the Son when they come to the Son. Why? Because they were given to the Son by the Father and the Son gives them eternal life and desires them to be with Him (Jn 17:2, 24). This means that those who truly come to Jesus will never be turned away. Nobody, and I mean nobody, who has truly desired to be saved and who has turned to Jesus has ever been turned away. All who come to Jesus, all who believe in Him, will be saved. What does the Scriptures say? "Whoever will call on the Name of the Lord will be saved" (Rom 10:13).
2. They will not be kicked out. Once a person has been accepted by Jesus, Jesus will never turn on them and cast them away from Him (Jn 6:38-39, 10:27-30). This means that once a person has truly been saved they cannot lose their salvation.
==The first part of that statement is simply not true. So either you don't understand Calvinist teaching or you are willfully misrepresenting it. God knows which is the truth and I will not play judge in that matter. Calvinists such as myself, RC Sproul, John MacArthur, and others do believe that "whosoever will may come" (Jn 3:16). However we also believe that nobody, and I mean nobody, will come on their own. For a person to come to Christ God must draw them to Him. Apart from that nobody will come to Christ. We believe in whosoever will and we believe that the elect will, the rest will not.
==I am really not sure what that statement means. I know of nothing in Scripture that teaches that a person can be saved, will be saved, apart from Divine election (Jn 6:44, Rom 8:29-30, Jn 17:2, etc).
