It appears to me that in Calvinism there is a very deep-rooted problem that amounts to heresy and I believe that it needs to be addressed.
And that is that the doctrine proclaims that a person is regenerated before they can come to Christ.
I will only say that if this is the case, then coming to Christ isn't necessary; since regeneration happens before it (and thus apart from it).
This is an abject heresy of Calvinism that must needs be corrected within its own framework of theology and doctrine.
I am not a Calvinist, but I do believe the Scripture reveals the following, namely this:
Before God created heaven, earth, and man a lamb was slain in the heavenly Tabernacle. This allowed God to create a sinful man and declared "let us make man in our image" that the "image of God" is not Adam, but Christ. There is a natural (Adam) and there is a spiritual (Christ - Heb. "Anointing") and that Christ bearing the image of the Father applies that image to the "new creation" to be born in the name of the Father whose plan it is to do the following:
Several things were determined when this heavenly Tabernacle sacrifice was made:
In the course of saving His covenant people there will be men of Israel (prophets) that are ordained to die in the course of giving the message of God to His people Israel, including the Prophet of prophets Jesus Christ.
#1. That the blood of all the prophets, which was shed from the foundation of the world, Lk 11:50.
That a Redeemer is ordained to die for the ransom of this covenant people Israel:
#2. Who verily was foreordained before the foundation of the world, but was manifest in these last times for you, 1 Peter 1:20.
That a people are ordained to life in the course of God's Redemptive plan:
#3. According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: 5 Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of his will, Eph 1:3–5.
That a kingdom is prepared to house this covenant people Israel with a King (God) at its center.
#4. Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: Mt 25:34.
That based on this book's "publishing" (not an actual book) in the heavenly Tabernacle sacrifice in pre-history, God has ordained names in this "book" in eternity and is only proceeding forward in time according to these names that are to be given life which at the appropriate time will receive life and life abundantly.
#5. And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world. Rev. 13:8.
That there are things "secret" (with the granting of His people the ability to find out these secrets), and things "secret" (that belong only to Him that are beyond His people's ability to find out its meaning.)
#6. That it might be fulfilled which was spoken by the prophet, saying, I will open my mouth in parables; I will utter things which have been kept secret from the foundation of the world. Mt 13:35.
That there are other particulars ordained and determined at the time of the heavenly Tabernacle sacrifice that relate to the Redemption of this people named in the book of life that apply to God's plan to redeem them, other "works."
#7. For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world. Heb 4:2–3.
That it was ordained to this Redeemer to suffer throughout His life culminating in one final suffering to atone for this people named in the book of life of the lamb.
#8. For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself. 27 And as it is appointed unto men once to die, but after this the judgment: 28 So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation. Heb 9:26–28.
That the foundation of this redemptive plan reveals a covenant or agreement to all the above with regard to this Redeemer who will endure all that is ordained for Him to endure and receive all that is due Him for enduring it, mainly, that the Father loves the Son, and the Son loves the Father and between them both a people will be loved and in this plan to redeem this people to the saving of their souls, the Redeemer will receive glory for the administration of this plan.
#9. I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me. 24
Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world. Jn 17:22–24.
Since God is Spirit, His image cannot be a natural man, there is a process played out in time to make this natural man a spiritual man and possessing the ability to bear that image in the continuation of that life and beyond. This requires a new creation to occur that makes the person named in the book of life and ordained to life to bear the image of the Son who bears the image of the Father thus making two into one before God.
The name for this [re-]creation is called regeneration. God has to generate a new creation, one that will have the capacity to bear His image. This people are then to be conformed to the image of Christ, not Adam as the natural man receives not the things of the Spirit of God.
16 For I am not ashamed of the gospel of Christ:
for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek. Rom. 1:16.
And there you have it. Salvation of God in a nutshell.
