One of the great issues we must reside in would be the sovereignty of God. It is God preeminence over all that makes being God possible. The Greek gods were all flawed and limited (imaginary too), but not Jehovah.
Another construct that many people have is that they make God in their own image. Or when faced with scripture, spoken by God, they can not accept what He has said and thusly they refuse to believe. Many want to perceive God as one whom they can comprehend and compartmentalize. Many are heaven laden with an idea of a God who is all love and no wrath. They make Him to be a kindly forgetful grandfather that passes over all wrongs. Thus look to say He is only love.
We must remember God is holy. His holiness thus dictates both His love and His wrath. Wrath defending His holiness and honorable name. Love with wrath because pure wrath is to be without love, we learn that without love we are nothing.
We also forget that we are sinners. We are the offenders unto God. He has no obligation to save us. We are not so loveable that He must save, all our righteousness is filthy menstrual rags. The Bible itself teaches that while we were yet sinners Christ did die for us. We were His enemy. We perpetrated all that is against His holy name.
Much of the misunderstanding of God today is the result of vending machine theology. Its of the over emphasis that God so loved the world, placing the emphasis on “the world” when the emphasis in upon God, as evidenced by whom is doing the action. We have made God in our own image.
