Do you trust me? Will you bet your life on it? Will you follow me as a result?
What God is after, why God made mankind the way he did, why things happen in historical time as they do is that God has a desire for mankind that requires the right answer to these kinds of questions from God. If one sincerely answers, "yes," God can share himself with that person. If one does not, he or she cannot be trusted with God's image, freedom, or even life itself, and will ultimately be contained and confined in a way not repulsive to God's omniscience.
The Bible demonstrates this from God's testing of Adam to Jesus' dealings with his disciples. God is looking for a response from people that demonstrates their "yes." What God is endeavoring to achieve is not the kind of thing that can avoid choices and the freedom to make them, for God's image cannot be God's image apart from freedom and choice. Within the Trinity, there is always a yes between the persons of the Godhead, there needs to be a yes between our persons and God's.
Calvinism is totally out to lunch when it comes to any understanding whatsoever about God's intents and purposes. The system doesn't begin to understand what we are here for, what God is trying to achieve or how. It is astonishing to me that it is considered intellectual in some corners when it is so fundamentally ignorant! On top of that, it assaults the character of God, making him out to be someone who cannot rise above the level of playing with toy soldiers.
God made mankind to know him, to walk with him, and to experience life along the the lines that he does. The agreement within the Trinity is a picture of what it takes for distinctive people to be able to do that. What must be understood and remembered is that as God puts the questions that matter to mankind, only faith in God can provide the answer he's always looking for.
