Dear Reader,
Romans 1-8 has made it very clear there is no salvation outside of Jesus Christ. Therefore, this leads to the natural objection in Romans 9-11 about National Israel. Since all the promises, covenant, scriptures were given to Israel and since they have rejected Christ does that mean that God's promise to Abraham concerning a nation from his own loins through Isaac is violated?
Paul approaches this objection in a threefold manner. First, he makes sure the reader knows that salvation is never a matter of physical relationship through physical birth or ethnic nationality but indivdiualistic, supernatural birth (Rom 9). Second, salvation comes through the preaching of the gospel (Rom. 10). Third, the fall of National Israel is temporary not permenant, she has stumbled but has not utterly fallen in regard to God's redemptive plan.
Furthermore, Romans 9:6-8 demands that Isaac provides the charactaerization for defining the children of promise. Isaac provides a two-fold characterization. He was chosen over Ishmael - elective choice. Second, his birth was supernatural without the assistance of either Abraham or Sarah as in the case of Ishmael.
The case of Jacob and Esau further characterizes God's elective choice. As with Isaac, the choice of Jacob over Esau as with Isaac over Ishmael was not based upon foreseen good or evil works by either. It was based solely upon God's elective "grace" or redemptive love.
God has the right to choose whom he wills as objects of His mercy versus objects of wrath (Rom. 9:15-18) becuase both "mercy" and "wrath" demand that the objects are being considered in a fallen and thus a condemned condition. Thus real justicie would simply call for the complete eternal punishment of all fallen mankind.
Not only so but election is unto salvation never unto damnation because they come into this world condemned already by their fall in Adam (Rom. 5:12) through ONE MAN'S DISOBEDIENCE MANY WERE MADE SINNERS (Rom. 5:15-19). Hence, God merely leaving Ishmael, Esau, Pharoah to their own depraved choices will naturally harden them the more they are exposed to light just as wet clay is more exposed to light hardens naturally in response to the sun.
Thus the illustration of the potter and the lump of fallen mankind as a lump of moist clay is a perfect analogy. The clay vessels of wrath fitted to destruction naturally harden by being left to themselves to go their own way. However, the vessels "afore prepared unto glory" are special objects of God's mercy.
Who are they? The preaching of the gospel in Romans 10 will make them manifest. You can know the elect by their response to the gospel (2 Thes. 1:4-5; Rom. 10:8-10). You can know the vessals of wrath by their persistant response to whatever light they are given (light of conscience, light of nature or light of the gospel). However, the elect or vessels "afore prepared unto glory" also come to salvation through the chosen means of preaching the gospel (2 Thes. 2:13-14) and that is precisely why we are called upon to go preach the gospel among all nations as that is the means that God makes effectually in calling out his elect.
God is perfectly just in permitting god hating creatures to continue in their own depraved choices but purely merciful in saving any of such.
The bottom line question in this debate will always come back to two questions:
1. Can God have mercy upon whom He wills among fallen mankind?
15 For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.
16 So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy.....18 Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth.
2. Can God do what he wills with fallen humanity?
20 Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus?
21 Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour?
22 What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction:
23 And that he might make known the riches of his glory on the vessels of mercy, which he had afore prepared unto glory,
24 Even us, whom he hath called, not of the Jews only, but also of the Gentiles?
