Hi Jaltus,
Thanks for your patience. I'm running so far behind on so many things that I'm forced to give a shorter reply to your question than I had planned. I am, however, getting more interested in this topic than I expected. This may become another one of my 14-pagers!
I quoted Dunn earlier:
""Those who love God" is a characteristic of self-designation of Jewish piety (a full listing in Cranfield, 424 n.4) usually following the typically deuteronomistic style, "those who love God and keep his commandments" (Exod 20:6; Deut 5:10; 6:5; 7:9; ect.; Josh 22:5; .....1Qh 16:13).
Dunn is referring to the Jewish contextual backdrop for Paul's comments in Romans 8:28.
Let's examine Deuteronomy 7 and use it as an example:
For you are a chosen people, holy to the Lord you God; the LORD you God has chosen you to be a people for his own possession, out of all the peoples that are on the face of the earth.
The corporate nature of the comment is difficult to miss. God chose a people, not individuals, to be his own possession. Individuals must enter the covenant to become part of that chosen people and possession.
The people are invited to enter the covenant and maintain it. Those who live by this covenant are
those who love him:
Know therefore that the LORD your God is God, the faithful God who keeps covenant and steadfast love with those who love him and keep his commandments, to a thousand generation, and requites to their face those who hate him, by destroying them; he will not be slack with him who hates him
"Those who love him" must continue to love him:
You shall therefore be careful to do the commandment and the statuses and the ordinances with is command you this day. And because you hearken to these ordinances and keep them and do them the LORD you God will keep with you the covenant and the steadfast love he swore to your fathers to keep.
This is an interesting series of comments that gives us insight into what Paul was thinking when he borrowed the words and imagery. The covenant God was intent on keeping was the one made to the "forefathers" (not to the members of the covenant) concerning a people that could be joined ("if you obey these ordinances, I will be your God and you will be my people") or left ("because you hearken to these ordinances and keep them and do them the LORD your God will keep with you the covenant" ). Paul speaks of this corporate election and the promise to the patriarchs as the rationale behind his letter to the Romans (15:8-9):
For I tell you that Christ has become a servant of the Jews on behalf of God's truth, to confirm the promises made to the patriarchs so that the Gentiles may glorify God for his mercy...
The promise to the patriarchs was that God would give them a new chosen people that would incorporate the Gentiles. That's why the issue of circumcision comes up. If there is another chosen people, HOW do we become members? Circumcision? Faith?
So now it's clearer why Paul brings Abraham into the debate. The "promise" of election was made to him, so he is the ultimate patriarch being spoken of. So who are the elect people being spoken of? The Jews? The people of faith?
Well, the answers to the questions are obvious now (to those who are not Reformed). The elect and predestined people, according to the promise made to the patriarchs, are the royal priesthood known as Christians. There's no such thing as an elect unbeliever, because, by definition, that person has not yet entered the covenant and is not among "those who love God."
So to answer your question, "those who love God" are most certainly blessed by him. They MUST continue to love God, as Moses has said (cf. Romans 11:20).
