One God Is More Than Enough
It may seem obvious to the point of going without saying, but one of the greatest advantages to Monotheism is the fact that there is only one God. We don't have to worry about whether the problem we're praying about falls under the jurisdiction of one god or another. We don't have to wonder if being in one god's favor will bring down the wrath of another god. Our Heavenly Father is a part of all things. He loves each of us with His whole heart. He is not fickle or changeable. We can go to Him with all of our problems and He will not turn us away or tell us that He doesn't handle that sort of thing. We worship only one God because one God is enough, more than enough, infinitely more than enough.
