The Puritan John Howe when preaching on the fall would recall seeing large palaces or castles that have fallen to ruins and there would be a sign hanging above the entrance saying something like “Centuries ago, such and such a king once dwelt here.” Then Howe would go on to say, “Now, as a result of man’s fall into sin, it is written over man, ‘Here, God once dwelt.’”
When man fell in the Garden of Eden he lost his original righteousness and thus his correspondence to God. God’s immediate response was to condemn man and put him out of Eden. No longer having correspondence with God man could no longer be together with God. The scriptures inform that it was the woman who first fell and then the man. Had Eve fallen alone, is there any reason whatsoever to believe that Adam would have been condemned along with her and both of them put out of the garden? Both logically and theologically, had Adam continued in his original righteousness, then he would have continued having correspondence to God and therefore would not have been condemned and put out of Eden.
Well then, one could speculate that perhaps Eve would have been allowed to stay in the garden with Adam even though she alone had fallen; after all she had become Adam’s wife. The Lord Jesus said, “What God has joined together let no man separate”. In our Lord’s statement we find the obvious doctrine, implicit, yet undeniable, that only God can separate what He has joined together and that is precisely what God would have done in this scenario. Eve would have been put out of the garden because she alone would have come under condemnation and she alone would have no longer had correspondence to God and, in fact, she would not have had correspondence to Adam either.
In this scenario they would have become unequally yoked in marriage, and God would have divorced them by putting Eve out of the garden alone. But some will argue that this is merely speculation. Since it never happened it cannot be known what God would have done. Speculation means: The act of theorizing. To speculate means: To form conjectures regarding anything without experiment (experience). To conjecture is to guess or to presume knowledge that is simply unknown.
Is it conjecture that man’s sin caused a separation between man and God? Few biblical doctrines are more sure than sin separates man from God. Is it conjecture that a just God would not punish an innocent man? The situation may be hypothetical but as to how God would have responded is sure. Adam would have continued in fellowship with God in the garden and Eve would have been stricken dead or put out of the garden, and since God put the both of them out of the garden for committing this offense together there is no reason, other than stubbornness of mind, to think that God would have done anything else with Eve had she alone fallen into sin.
But God in His everlasting lovingkindness sent His only begotten Son into the world so that whosoever believes in Him shall come out from under God’s condemnation and once again have correspondence to God. The righteousness of Christ Jesus is the possession of all those truly born-again. So then, they, once again, have correspondence to God in their spirit. They are granted eternal life and will forever dwell with God.
However, they no longer correspond to those children of Satan who refuse repentance. If God’s remedy for a failure to correspond to a righteous being is to put the unrighteous, condemned soul out, then that is precisely what must be done here. Notwithstanding Paul’s temporary injunction to the Corinthians that if the unbelieving spouse “consents to live with” then let them stay. The great apostle laid out four conditions of this consent, which if not followed meant that the unbeliver did not give their consent. So, Paul provided a short “grace period” with this temporary injunction so that the grace of God in salvation might come to the unsaved spouse as well. Some time is necessary to see whether or not the unbelieving spouse softens or hardens to the gospel of grace.
Then after an appropriate amount of time divorce is inevitable as Paul subsequently commanded the Corinthian believers “Do not be bound together with unbelievers”. And the great apostle gave this command because the two no longer have correspondence to one another. Then Paul quotes the scriptures saying, “Come out from their midst and be separate, says the Lord. And do not touch what is unclean; and I will welcome you. And I will be a father to you, and you shall be sons and daughters to Me, says the Lord Almighty” (2 Cor. 6:14-18). Saints who are presently bound in marriages with unbelievers should be agreed that marital separation from such unions is inevitable, and seek to know the mind of God concerning the steps which they should take.
Adam and Eve stayed married to one another because they continued in their correspondence one to another throughout their entire lives (they fell and remained fallen together), but when a marriage consists of one born-again person in whom there is no condemnation and one child of Satan who is already condemned by God a divorce is the biblically mandated remedy. It is God that has separated them when He brought only one of them out from under His just condemnation. The one condemned should be called to repentance, and if they refuse they should be put out of the marriage as they no longer have correspondence with their righteous spouse or with God who dwells within the believing spouse.
Marriages between saints and unrepentent sinners have it written over them, “Here, God has never dwelt.”
