Albion, you may have missed my response to your first question:
Yes, we begin with the idea of God preserving for Himself a group called the elect who obtain salvation, they do not save and preserve themselves from being Satan (Baal) worshipers, God does this for Himself alone, that salvation will be according to grace alone.
Romans 11, also includes the gentiles along with the jews.
4 But what does the divine response say to him?
“I have reserved for Myself seven thousand men who have not bowed the knee to Baal.”5 Even so then, at this present time there is a remnant according to the election of grace. 6 And if by grace, then
it is no longer of works; otherwise grace is no longer grace. But if
it is of works, it is no longer grace; otherwise work is no longer work.
7 What then? Israel has not obtained what it seeks; but the elect have obtained it, and the rest were blinded. 8 Just as it is written:
“God has given them a spirit of stupor,
Eyes that they should not see
And ears that they should not hear,
To this very day.”
9 And David says:
“Let their table become a snare and a trap,
A stumbling block and a recompense to them.
10 Let their eyes be darkened, so that they do not see,
And bow down their back always.”
And the chapter ends with
28 Concerning the gospel
they are enemies for your sake, but concerning the election
they are beloved for the sake of the fathers. 29 For the gifts and the calling of God
are irrevocable. 30 For as you Gentiles were once disobedient to God, yet have now obtained mercy through their disobedience, 31 even so these Jews also have now been disobedient, that through the mercy shown you Gentiles they also may obtain mercy. 32 For God has committed them all both Jew and Gentile to disobedience, that He might have mercy on all.
33 Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable
are His judgments and His ways past finding out!
34 “For who has known the mind of the Lord?
Or who has become His counselor?”
35 “Or who has first given to Him
And it shall be repaid to him?”
36
For of Him and through Him and to Him are all things, to whom be glory forever. Amen.
How far you go with what God is and does with His creation has to do with how you understand 'all things' fit into the creation.
