Gen 4:6-7: And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen? If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him.
“I don't see how God can plead with all mankind to come to Him, full knowing that he's determined that some would not come to him. The problem I have with your theology is that it forces us to see God as a deceiver.”
We could make a similar distinction with a father and a rebellious son. Sometimes teen-agers have to learn things the hard way. So, the father gives the son permission to drive the car with the knowledge that the son will most likely speed. The rebellious son is jailed for one night for reckless driving. The father knew as much and let the son “sweat it out” overnight. The father’s prescriptive will is: Do not speed. The father’s decretive will is: I will permit you to drive. I will permit you to be in prison. We do not say the father is schizophrenic. Nor would we say he has two “wills”. And we would not accuse him of deception. Likewise, there is no deception in God; he is speaking the truth (see the first posting).
Yet, in a real sense there is a difference: man, being born in sin, deserves nothing. God is not morally bound to rescue him from his physical plight let alone man’s spiritual plight.
