Failing to properly define the word "God" prevents us from understanding Him, the most high God, and all other lesser Gods/gods.
And this misunderstanding leads into all kinds of errors, like the false doctrine of the "trinity." In this video, you'll see how Jesus can be "God," but not "the only true God," Who is His Father alone.
In this video, I also provide you an opportunity to test your definition of "God" to see if it fits the Scriptures.
