Unbelievers ask the question: ^How do you know that you are serving the <i>real</i> God.^.   Here Moses is addressing that question by telling the ChildrenOfIsrael that if there are other gods, their God is supreme over any others that might be.   <p>When we hear Jesus proclaiming that all power in heaven and earth is His, He is saying that He is AlmightyGod.<p>A true Christian has NO doubt about Christ Jesus being LordOfLords and KingOfKings.
