If the message was not in the beginning then you will have to explain Genesis 3:15, cross-reference it with Isaiah 53, and as you see that the message was revealed and fulfilled in the crucifixion of Christ. God in his sovereignty knows all this, he is omniscient, he calls what is not as it is. Didn't he elect before the foundation of the world and doesn't this implies that he is absolutely sovereign? I think I understand what you are trying to convey, but if this message came sometime after, are you saying that one day this came to his mind about salvation, if yes, then what you are saying prior to it coming to his mind he did not know about this message, which I am seeing in the way you are thinking and if that is the case then according your view he cannot be omniscient, therefore, he cannot be absolutely sovereign.
You continued with... your intention in saying this is that although there is a deliverance in understanding the gospel it is not an eternal deliverance, but a timely deliverance. Please elaborate because I do not understand how this relates to the statement to made right before making this statement.
How can God give one the indwelling of the Spirit when man is not yet forgiven? Yeshua said to the man born blind, your sins are forgiven, the Spirit was not indwelling in him or was it? As previously stated, God reaches out to man because man would not seek God, therefore, the Spirit of God uses people like us to minister the Gospel of Salvation so that they can see the love of God and he quickens them to respond at that moment, man respond because the Spirit of God quickened him, but it is his decision if he would serve. When time of judgment comes those who reject Yeshua will have not excuses and cannot say they never heard the Gospel of Salvation, why you think the Scriptures say today is the day of Salvation, not tomorrow, I can safely say the moment one hears it he needs to respond with an acceptances of the atonement that Yeshua did on the cross, but he will decide.
The Spirit of God recently enlightened a scriptural truth. If you read the story of Yeshua and Nicodemus, when Yeshua mentioned born-again Nicodemus answered with, how can a man be born when he is old, can he enter his mother's womb a second time? And after he asked, how can these things be? Yeshua answered, with the following... art thou a master of Israel, and thou knowest not these things? This was an earthly thing that Yeshua told him. From the way I understood this, Nicodemus should have understood this from the free woman and the bond woman. Born-again is the moment that you accept, it is at the moment one becomes save. I hope I am not diverting, but the way you wrote was not clear to me. What made Abraham the father of faith is that he responded with faith, so our respond has to be with immediate faith to be saves.
If I understand you correctly, you do not believe that a person can lose their salvation, in other words, once saved always saved and if that is what you believe, you cannot substantiate that through the Scriptures, that is the doctrine of man. The Word of God is clear that a man can lose their salvation.
As I previously stated, Yeshua died for mankind not some but all and by man being quickened by the Spirit of God he respond with a decision to accept the atonement or to deny the atonement. I think I previously explain to you Heb 10:12-14 and if I didn't let me know.
