Does God have Faith? If God Himself never takes risks then He has no need of faith. Logically then, since Faith is the primary requirement of Christianity He is asking us to have something he Himself does not have.
For God to take a risk means that while it might be possible that He could know everything, He chooses not to know, or the future is not knowable.
The logical inconsistencies presented by the Calvinists, essentially requires God to be the creator of evil. Argument goes: God created everything, evil exists ergo God created evil. There is no escaping it. The pretzel logic required by Calvinists is amusing. For any other possible creation of evil means that God is not the only creator ergo God did not create everything.
Humans have been putting God into boxes of human creation since the beginning of time itself. They use such noble words as all powerful, all knowing, and still they want to limit God to how they themselves understand those terms. God has no freedom to choose under those terms. He "must" always get His way and He "must" always be unchangeable, and he "MUST " do all those things that such people want of their God. Such a God has no need for faith he gets whatever He wants regardless of any other factor anywhere in the universe.
I subscribe to what is called Open Theism. Look it up in Wikipedia if you have never read about it before. The transcendental qualities of God are not limiting factors but tools He can use when and If He chooses. The single most important thing about God that we humans can participate in is Faith. He takes risks and we do also. This does not mean that God will necessarily always get what He wants, but He can in fact put plan 'B' into effect if plan 'A' does not work out.
God never offered eternal security to us, never intended for that condition because it means a death to our growing and changing and gaining maturity. Eternal security is Satan's imitation of God, set out to prevent us from ever being the fully grown, fully mature individuals. There are far too many baby Christians, people who have no ability to understand, they are theological robots following orders from God.
When and if we make mistakes, we repent, God forgives us and we move on. Making mistakes is the result of risking, it is the method by which we learn and grow and taking the risk out of life would be a tragedy.
