Anyone who believes in God has a perception and a definition of Him. But God has an identity outside His attributes. He is not God because of what He does but because of who He is. He is a personal God. Self-existence (having no creator) is not an attribute of God. It is who He is. Had He not created the world and human beings with which to interact, He would be no less God. Even if God does nothing other than be who He is, He does not lose His identity.
The identity of God is constant. By His very nature, He is God. There cannot be more or less of Him. All His actions, attributes and manifestations come from his nature. Therefore, God is God, not because we have agreed He exists. God is God because of His identity of self-existence. His existence is not contingent upon our human thinking.
In the original design, mankind could not separate the being of God from the doing of God. He is one integrated Being of doing. If we dismantle a car, we have parts of the car but no longer have the car. When we break down a vehicle to its parts, it loses its identity, because its function is gone. An engine has no value sitting on blocks. A bucket seat has little value outside the vehicle. But when we put all the parts together, they become a car. Cars gain and lose identity. As much as we want to take God apart, He is not built like anything we can comprehend. He is a total Being.
The Bible describes God as a Person. We have almost lost this perspective, because so many of us think of Him as a good ideology. We have relegated Him to a misty haze or a mystical tyrant, waiting to whip us for our mistakes. Today, God is more often considered a thought or figment of the imagination than a person! Our perception of Him matters, because it defines our relationship with Him.
The Hebrew word for father is Abba. God is Abba, first. This is the starting point for experiencing God. If we wish to know Him, we must begin by understanding His identity as the Father. And we can only know our identity by first knowing the fatherhood identity of God. This is not the same as the universal fatherhood of God (with all human beings considered children of God because He is their Creator). The fatherhood of God is a positional identity. God does not act like a father; He is our Father. Just as He is self-existent and eternal, He is our Father.
Christianity carries no meaning apart from the understanding of God as Father. We must understand that God is relational. He is seeking a spiritual relationship that happens through a communion of intimacy between a Father and a child.
