Believing is not a meritorious action.
So we're supposed to blindly accept that "believing is not meritorious", just because you CLAIM it's not?
1. deserving praise, reward, esteem, etc.; praiseworthy:
Sounds PRECISELY how one would describe "faith".
It is not a work!
Yes, Paul repeatedly contrasted with works. But the faith Paul spoke of is NOT the same faith Arminians believe in. It is the God-given gift that CAUSES (necessarily) the elect to believe. So you can't appeal to Paul when (IMO) he's not referring to what you believe.
There is no "respecting of persons" in conditional elections because all are equally welcome to believe and able to believe when convicted and enlightened by the Spirit through the gospel. Any man woman from any nation, of any status is able to believe the gospel!
You remind me of an old joke, which is based on deflection:
Q: "I have two coins totally 55 cents, and one is not a nickel. What are the two coins?"
A: "One coin is a fifty-cent piece. The OTHER coin is the nickel".
In the same way, you are deflecting away from the meritorious action.
You say "all are equally welcome to believe". If that's your theology, then being "welcome to believe" is not meritorious.
You say "all are able to believe the gospel" (which I don't find Biblical). But if that's your theology, then "being able to believe" is not meritorious.
But then from there, some actually DO believe, and some don't. And if the difference between believing and not believing comes from men, and not God, then it is by definition meritorious.
And that makes God "a respecter of persons".
