I will look closer into it. Maybe respond to him later if I know what to say.
I wonder what you would say as a Calvinist since you don't know Christ died for him. You can't say Christ died for him for an example, or you can but that would be dishonest.
There are multitudes of such examples, people who are under the impression that it is their 'acceptance', the virtue of their decision, that makes all the difference. I have a tendency not to answer, not only because of the cacophony of resistant voices that will join the fray against me, in the presence of a new believer, but because of the fact that the very mindset of most new believers cannot conceive of the thing I hope to convey.
Even though I think very highly of you, compared to most who see problems with Calvinism, as you come across generally even-tempered and non-arrogant, and possessing of a willingness to consider multiple angles and minds, even you demonstrate a mindset that is unable to consider the will of man as actually incapable of anything apart from God's purpose and actions. Thus I don't think they, or you, or the new believer, likely to get a lot out of what I would say to such a person.
But I will try to say it as best as I can, without going on too long: My concern has for quite a few years now, not been a question of whether I am one of those who will be in Heaven. That has been overrun with the joy of knowing that God is altogether pleased with the work of his hands, with his particular creation, with what he has done (which is also what he is doing), and the confidence that he will complete what he has begun, and the anticipation of seeing him as he is, and knowing him as I am known. These things (and other related things) are the focus, or to say it more accurately, HE is the focus —this life and the next are about him, not me, and not about my safety.
When I say, "the confidence that he will complete what he has begun" I expect that you (or those more antagonistic than you) will protest, "but how do you know whether he has begun it?". I say, the same way anyone knows: It is not by the integrity or sincerity of one's asking Jesus into their heart that they are saved, but by the work of God. But the witness and comfort of the Spirit of God to my spirit is undeniable at this point.
This reminds me King David's situation, where after he takes a census, which was evil in God's sight for him to do, God gives him a choice of judgement upon Israel by famine, or by their enemies, or by the hand of God; and David said,
"Let me fall into the hands of the Lord, for his mercy is very great; but do not let me fall into human hands.” I am at God's mercy, regardless, as to my eternal destiny; I say it is good that God is the one to choose, as my choices are stupid, helpless, ignorant and self-deceived, but God's choosing is full of mercy. I don't even really know what I am choosing when I choose, but only how things look to me at that moment.
