Romans 10:1
1Brothers, my heart’s desire and my prayer to God is for Israel, that they may be saved.
Wesley: my prayer to God is, that they may be saved—He would not have prayed for this, had they been absolutely reprobated. The “them” are Israel from chapter 9. Heart’s desire and prayer are not theatre: Paul asks God to save a people he still treats as savable.
Classical Arminians take the prayer as evidence against unconditional reprobation. You do not plead for those God has already, from eternity, shut out of mercy. The same apostle who wept in 9:1–3 now prays; the will of God, Wesley will say at v. 13, is that all should savingly call upon him. Prayer here is sincere means toward a salvation.
Paul’s heart’s desire and prayer is that they may be saved. The grief of 9:1–3 has become petition. Prayer for Israel does not retract the purpose of election already named; it is how God has appointed his servants to seek a people.
Calvin will later treat calling on the Lord as the appointed means, not a proof that every Israelite is elect. Paul can pray for kinsmen, as Moses did, while still knowing that not all who are of Israel are Israel (9:6). Desire is true; so is a remnant. Prayer and particular election stand together.
