Protestant,
There is a basic truth to the premise that Arminians impose (wittingly or unwittingly) their view of fairness on God. It is perfectly logical. After all, what more can we expect with our relationships besides fairness? Fairness implies a sort of equality. We all have a level playing field. No one has it better or worse than somebody else. There is no "playing favorites". Would not life be great if fairness ruled; if everyone was fair to each other all the time? The truth is that fairness is a myth. Our idea of fairness is tainted by our presuppositions and experiences. What I consider to be fair you may consider to be favoritism and vice versa. To the Arminian the epitome of fairness is God. Surely with God all people are equal. The Arminian will point to John 3:16 and happily proclaim, "For God so loved the world!" How more fair can God be? He loves the whole world! But contrast that against Romans 9:13, "As it is written, Jacob have I loved, but Esau have I hated."
In another thread the accusation was made that consistent Calvinism leads to hyper-Calvinism. Well, consistent Arminianism leads to Open Theism and/or Universalism. After all God is fair. Another poster wrote, "Shall not the God of all the earth do right?" Do right according to whose definition of right? Are we really going to impose upon God our idea of who He should be and how He should act? Does God answer to His creation?
The fact is that God is not fair. If God was fair He would either condemn all or save all. Instead of being fair, God is merciful and just. He displays great mercy and forgiveness towards those who call on Him by faith; while dispensing wrath on those who reject Him. The Arminian would agree with this and counter by saying that is proof God is fair because each person has an equal chance to either accept or reject Him. But is that true? Back in Romans 9:11 Paul wrote about Jacob and Esau, "For the children being not yet born, neither having done any good or evil, that the purpose of God according to election might stand, not of works, but of him that calleth;". God's choice was made prior, and independent, of human choice.
The Arminian's view of God's fairness is flawed. Even when God said in Isaiah 1:18, "Come now, and let us reason together, saith the Lord" He was not painting the picture of sitting down at the negotiation table with sinful man and trying to come to a fair conclusion. God was telling Israel to stop their excuses and see themselves as He saw them and to accept His remedy. God is doing the same today. He is not negotiating with sinners. He commands sinners to repent (Acts 17:30). Jesus displayed a great amount of intolerance when He said, " I am the way, the truth, and the life: no man cometh unto the Father, but by me" (John 14:6). God's way or no way. How is that fair?
God is not fair. But praise be that He is merciful.
