FWers don't believe the Potter hasn't any rights over his creation, in spite of what Paul taught. All the rights belong to his clay pots. The Potter exists to serve his pots.
Romans 9 includes three overlapping TOP.
TOP #44: Although many Jews reject the Gospel/Christ, God’s covenant with Abraham did not fail, because the children of Abraham includes (spiritually circumcised) Gentiles. [Rom. 9:1-33, cf. TOP #24] In verses 1-5 Paul noted how sad it is that those who are part of the human ancestry of Christ reject him as Messiah (and are therefore not Abraham’s spiritual children). Paul explained that the reason Israelites are not saved is because they ignored God’s purpose in s/e or POS involving mercy (v.11-15) on those having faith in Christ (who is to be praised or glorified forever as God over all, amen) and instead pursued righteousness by works or obeying the law (v.30-33).
TOP #45: God has the power to determine what is required for salvation, and He is just to destroy those who resist His will. [Rom. 9:16-29] After noting (in verses 6-13) that God had chosen which one of Rebecca’s sons (through whom Messiah’s lineage would be traced) before they were born (cf. Mal. 1:2-3) . The word translated as “hate” (miseo) is the same as in Luke 14:26 with reference to family, so a better translation would be “preferred”: loving Jacob/hating Esau refers to God preferring that Jacob’s descendants serve as the heritage for Messiah rather than to individual salvation.
31. Romans 9:14-16 stresses that s/e depends on God’s mercy rather than being achieved by human effort (#12), although the preceding context has shown that (the non-meritorious condition of) faith is involved, which truth can be stated as “God initiates; sinners cooperate—or not”, because of MFW.
32. Romans 9:17 refers to pharaoh in Exodus 9:13-35 as an example of someone whom God allowed to oppose His will so that His power might be manifested by the plagues. The OT passage indicates that pharaoh was conscious of his sin but “He and his officials hardened their hearts” (v.34b).
Paul cites Scripture (Exo. 10:1) saying that God hardened Pharoah’s heart for the purpose of revealing divine power, and then he notes (v.20-21) that a potter has the right to make pottery for various uses.
TOP #46: Those who reject God’s will/POS will experience His wrath and destruction. [Rom. 9:22-29] Sodom and Gomorrah are cited as examples, and Paul cited Isaiah saying (in Isa. 10:22-23) only a remnant of Israel would be saved.
