Is god a concept

There are many gods and deities. But regarding the creator Jehovah God, The Bible mentions of him in the following verses: Psalm 83:18, "May people know that you, whose name is Jehovah, you alone are the Most High over all the earth." Psalm 100:3, "Know that Jehovah is God. He is the one who made us, and we belong to him." Then at Revelation 4:11, "You are worthy, Jehovah our God, to receive the glory and the honor and the power, because you created all things, and because of your will they came into existence and were created.”
