PM, can you provide even one scripture reference that clearly says that? - I mean clearly like Acts 13:48 says that a certain number of them were ordained to believe, rather than chose to.
You are unecessarily making a distinction between a person who "chooses" to accept the call of the holy spirit and one who is "ordained" to salvation. If you follow the commandment of the Lord and choose to believe and receive, then God will sanctify and ordain you to salvation. In our minds it would appear that the ordination followed our acceptance of Jesus, but in reality, since God knew this was going to happen before the foundation of the earth, God sanctified your choice and ordained you to salvation based upon his foreknowledge. Jesus said that whosoever comes to him he will in no wise cast out. Now it is true that the Father gives them to him, but it does not follow that God does not honor our choices and ordain us according to his foreknowledge. If he didn't want us to be saved, he could always kill us off before we are "destined" to accept him, but he doesn't do that. No, he sees the choices we make now and he sees them from the foundation of the earth and if he wants us to be saved then he ordained us from the foundation of the earth.
Your picture of God seems to me to limit Him to time, but He is not limited to time. He exists everywhere both in time and in space. He is in the past, he is in the present and he is in the future. He is the one "who is, who was, and who is to come." God knows the number of those who will believe. God has ordained them to eternal life based upon both his foreknowledge and the good pleasure of his will. Calvinists seem to me to limit his ordination of belivers based solely on "the good pleasure of his will." They are only half right.
I am working my way down the new posts so it may have been answered but I too would like to see a direct scripture reference
