According to the Bible, the fact that there is only One God is something that even demons believe.
You believe that there is One God. Good! Even the demons believe that—and shudder (James 2:10).
So, if it’s obvious even to those who hate God, how much clearer should it be to those of us who love God, that he is one? Now that you understand that for you to know that there is One God puts you on the level of beginner Christianity, you can see that it’s no big deal to understand it—no big deal at all!
In the Epistle to the Hebrews, the author rebuked believers for not maturing beyond the “elementary truths of God’s Word,” among which he listed “faith in God.” In other words, he chastised them for being so slow in their growth and went so far as to say that the foundation of “faith in God” was for immature and new believers. Here’s the passage we’re referring to:
... though by this time you ought to be teachers, you need someone to teach you the elementary truths of God’s Word all over again... let us move beyond the elementary teachings about Christ and be taken forward to maturity, not laying again the foundation of... faith in God (Hebrews 5:12;6:1).
The apostle who wrote this actually wanted Christians to leave the teaching about God behind them! Why? So that they could finally become the mature disciples he expected them to be. That means that if you can put the information in our books behind you, it will be time for you to begin maturing as a follower of Christ!
It might seem like a big deal to be a monotheist, but the truth is that you don’t even have to be enlightened by the Holy Spirit—common sense suffices. It’s clear from the testimony of the mountains, valleys, plains, rivers, oceans, plants, animals, trees, sun, moon, stars, and planets seen all around us that one all-powerful God exists. The harmony and design point to one source—one wise and loving origin.
The Word of God says that it’s plain who God is even from the natural environment. No special revelation is required. The judgment of Paul the apostle is that mankind has turned from its original, primitive, simple knowledge of God and has suppressed the evidence, denying him altogether.
...what may be known about God is plain to them, because God has made it plain to them. For since the Creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse. For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools and exchanged the glory of the Immortal God for images made to look like a mortal human being and birds and animals and reptiles... (Romans 1:19-23).
They exchanged the truth about God for a lie... Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind (Romans 1:25,28).
In the previous passage, the “Immortal God” is mentioned. We know that this term refers to the One and Only God of whom, in another passage, it says “who alone is immortal” (1 Timothy 1:17; 6:16). Immortality (exemption from death) is an exclusive characteristic of the One God. There’s only One who never has nor never could ever die--and it couldn’t be Jesus. He died at Calvary.
