Summary: How many Gods are there? If there is only one God then does it matter how we worship Him? While it is true that there is only one true God, the Bible makes it clear that there are many gods.
Purpose: To see that God is superior to all things.
Aim: I want the listener to gain more reverence for God.
INTRODUCTION: How many Gods are there? Over the years, I have heard many people say that because there is only one God it does not matter what church you go to in order to worship Him. If there is only one God then does it matter how we worship Him? While it is true that there is only one true God, the Bible makes it clear that there are many gods. The Hebrew name El-Elyon tells us that God is "The God Most High" which implies that there are other gods.
The question is NOT if you believe in God--the question is: Which God do you believe in?
Last week we finished looking at El Shaddai so I want you to notice a verse where David uses both last week’s and this week’s names for God: Psalm 91:1 He who dwells in the shelter of the Most High [El-Elyon]will abide in the shadow of the Almighty [Shaddai "The all-sufficient God who protects and provides"]. (NAU)
In other words, if you are not trusting in "The Most High God" God is not your protector.
"God Most High (אֵל עֶלְיוֹן, ˒ēl ˓elyôn) This title [uses about 50 times in the OT] is formed by the conjunction of the noun אֵל (˒ēl, "God") and the qualifying noun עֱלְיוֹן (˓elyôn, "high"), the latter deriving from the verb עָלָה, ˓ālåh, meaning "to ascend, to mount up." 
So the one true God is El-Elyon--the God who is "The God Most High"
not just a god who ascends.
Let’s learn together how God, the one true God, is greater than all other gods.
I. El-Elyon’s Position
In short, El-Elyon means that God is absolutely sovereign. A.W. Pink gives us a good definition of the sovereignty of God: "God does as He pleases, only as He pleases, always as He pleases."
"When a cowboy applied for health insurance, the agent routinely asked if he had had any accidents during the previous year. The cowboy replied, ’No, but I was bitten by a rattlesnake, and a horse kicked me in the ribs. That laid me up for a while.’ The agent said, ’Weren’t those accidents?’ ’No,’ replied the cowboy, ’they did it on purpose.’ The cowboy realized that there are no such things as ’accidents.’ How about you Christian? Do you believe that some things catch God by surprise?" 
Psalm 115:3 But our God is in the heavens; He does whatever He pleases. (NAU)
After Job finished with all of his great suffering, he told God what he learned: Job 42:2 "I know that You can do all things, and that no purpose of Yours can be thwarted. (NAU)
Now let us look at some ways that God exercises His authority.
A. El-Elyon is over creation
Psalm 97:9a For You are the LORD Most High over all the earth... (NAU)
Psalm 83:18 That they may know that You alone, whose name is the LORD, are the Most High over all the earth. (NAU)
B. El-Elyon is over the curse on creation
Sin has corrupted all of creation which is why we have earthquakes and hurricanes, but El-Elyon is still in control.
