God is the alpha and the omega. The beginning and the end. He always was, and always will be.
People try to find understanding of such a God by themselves. This is the first mistake. Understanding God has little to do with mad-made philosophy or logic. Logic is limited to the boundaries of a mans mind- period. Cherry picking scripture verses is another fatal error. Choosing to see our perceived flaws in scripture is still choice. Limited understanding confounds a person who is trying to figure it all out by themselves. Mans nature is flawed and ripe for corruption, therefore, add poor choices with a closed mind and heart, and you will convince yourself that God does not exist. You have had blinders on your eyes all your life. These are called scales in the Bible. Knowing Him, removes them so that you can see. To know God, you first have to ask Him. Talk to him, as yourself. He promises to make himself known to you and He does not lie, but you have to have an open heart.
Is the question valid? Sure. Does it lack understanding? Yeah. But with the right mindset, it's a start. If I told you He wants to know you too, that would probably make you wonder. But He really does. He is not a punisher or the great equalizer in the sky...The world doesn't want you to believe or know Him, but many don't understand even what the world truly is either. God, by definition, is supernatural, and there is a spiritual war going on right now. If you were able to see the forces pitted against you, you would die of sheer hopelessness alone.
