This seems like it would apply equally to the "spirit" of a Calvinist as the "spirit" of a non-Calvinist. Which suggests that those claiming to become atheists because Calvinism left them no way to be sure that they were one of the ELECT, probably had a problem having nothing to do with Calvinism.
From your response, "The Spirit did not bear witness with their spirit that they were a child of God."
So what would your prognosis be of such a person? Do they have a bad understanding of some point of Theology?
The scripture I quoted has nothing whatsoever to do with Calvinism or the ELECT, as they are not mentioned.
The context is about:
- Those who are in Christ Jesus.
- Those who are in Christ Jesus who do not walk according to the flesh, but walk according to the Spirit.
If a person is living there life according to the Spirit, then the Spirit bears witness with our spirit that we are children of God.
Here is the context —
There is therefore now no condemnation to
those who are in Christ Jesus,
who do not walk according to the flesh, but according to the Spirit. For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death. For what the law could not do in that it was weak through the flesh, God did by sending His own Son in the likeness of sinful flesh, on account of sin: He condemned sin in the flesh, that the righteous requirement of the law might be fulfilled in us
who do not walk according to the flesh but according to the Spirit.
For
those who live according to the flesh set their minds on the things of the flesh,
but those who live according to the Spirit, the things of the Spirit. For to be carnally minded is death, but to be spiritually minded is life and peace. Because the carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be.
So then, those who are in the flesh cannot please God.
But you are not in the flesh but in the Spirit,
if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His. And if Christ is in you, the body is dead because of sin, but the Spirit is life because of righteousness. But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you. Therefore, brethren, we are debtors—not to the flesh, to live according to the flesh. For if you live according to the flesh you will die;
but if by the Spirit you put to death the deeds of the body, you will live (have eternal life). For
as many as are led by the Spirit of God, these are sons of God. For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by whom we cry out, “Abba, Father.”
The Spirit Himself bears witness with our spirit that we are children of God, Romans 8:1-16
