The word God is the indication that there is the word and purpose, that there is a God. The word God gained currency because of the existence of God. A word emerges from the tongues of people in order to indicate an object or an idea, which they have cognised. If there was no God, the word God would not have originated and gained currency. A non-existent entity will not have a label to identify it. You may see God or you may not, but the word God is the proof that there is a God. God is eternal power, omniscient and omnipotent.
