Rain was not superficial, but absolutely necessary for farming and sustenance. So if God would be so moved by their earthly needs, why would He be less interested in their eternal needs?
Calvinist, James White: “Surely it is part of modern evangelical tradition to say, ‘God loves you and has a wonderful plan for your life,’ but providing a meaningful biblical basis for this assertion is significantly more difficult.” (Debating Calvinism, p.265, emphasis mine)
James White: “Everyone knows John 3:16, and that’s the problem. So many are familiar with the verse that very few stop to consider the traditions that have been packed very carefully into its constant and often acontextual citation.” (Debating Calvinism, p.376, emphasis mine)
Calvinist, Jay Adams: “As a Reformed Christian, the writer believes that counselors must not tell any unsaved counselee that Christ died for him, for they cannot say that. No man knows except Christ himself who are his elect for whom he died. But the counselor’s task is to explain the gospel and to say very plainly that God commands all men to repent of their sin and believe in Jesus Christ.” (Competent to Counsel, p.70, emphasis mine)
One member of The Society of Evangelical Arminians: “I agree with this idea that you are proposing of focusing on the doctrines of the goodness of God. One of the key things that I have constantly pushed in my discussions with Calvinists is that Arminians center their theological distinctives on the righteousness of God, whereas Calvinists center their distinctives on God’s sovereignty. It is not that one precludes the other, but that the center of discussion will ultimately be revealed as one or the other. I believe this is one of the reason why Calvinists ultimately gravitate to Romans 9:20 when challenge about how their doctrine depicts God’s righteousness. Their interpretation of that verse has provided an escape for them by their implicit suggestion that we are not allowed to examine the righteousness of God in salvation. We must just accept it. Arminians (and other non-Calvinist) begin at the goodness/righteousness of God and move outward from there.”
I believe that an emphasis on the goodness of God, will have a net effect upon Calvinists as charging back with Universalism, even though neither party advocates it, as both parties fully agree that God is too good not to punish wickedness. So any such response would be more of a knee-jerk reaction. Again, as emphasized by Michael Brown, Arminians are not suggesting that Calvinists reject the goodness of God, but rather that their theology of Preterition invariably degrades it, especially when you view it in light of the casual indifference of the pass-by theology of the priest and the Levite of Luke 10:30-31.
