Geisler presents an analogy to help clarify his proposed distinction.
Geisler continues: “An illustration is in order. Suppose a young man (whom we will call Jim) is contemplating marriage, and knows two young ladies (whom we will call Joan and Betty), either of whom would make a good wife for him. As a Christian, he has three basic choices: (1) to propose to neither of them; (2) to propose to Joan; or (3) to propose to Betty. Bear in mind that the young man is under no compulsion. There is nothing outside his own will that places demands on him to choose any one of the three options (or any other one). Suppose further that the young man happens to know that if he proposes to Joan she will say yes and if he proposes to Betty she will say no. Suppose, then in accordance with this foreknowledge of how she will freely respond, that Jim chooses to propose to Joan. Suppose even that he knew she would be reluctant at first but with persistent and loving persuasion she would eventually—freely—accept his offer. The decision on his part was entirely free, uncoerced, and not based on anything outside himself. But it was also a decision that was with full knowledge of the response and which respected the free choice of the person to whom he decided to propose. This is analogous to what moderate Calvinists believe about God’s unconditional election.” (Chosen But Free, pp.69-70)
It seems evident that Jim chose to propose to Joan (as opposed to Betty) because he knew that he could get a yes from her. So why couldn’t you say that he chose her “based upon” and “dependent on” his special knowledge of her response? In other words, I’m simply not understanding Geisler’s asserted dichotomy.
Geisler adds: “It is clear, of course, that God chose us before we chose to accept Him. And our decision to accept His offer of salvation is not the basis for His choice of us. We did not choose Him--either first or as the basis of His choice of us.” (Chosen But Free, p.74)
I simply do not understand how the illustration has clarified the distinction between “based on” vs. “in accord with.”
