There Is Only One God
As concerning therefore the eating of those things that are offered in sacrifice unto idols, we know that an idol is nothing in the world, and that there is none other God but one.
For though there be that are called gods, whether in heaven or in earth, (as there be gods many, and lords many,)
But to us there is but one God, the Father, of whom are all things, and we in him; and one Lord Jesus Christ, by whom are all things, and we by him.
I Corinthians 8:4-6
Islam says Allah is the only God, but Allah is the moon god of the Arabians. Their god is at the top of every mosque – a crescent moon. Their Kaaba stone in Mecca is a meteorite, so they worship nothing, just as Paul wrote – the moon and a meteorite!
The Hindus are more honest – they have millions or billions of gods – total confusion by imaginations gone to seed. Buddhists are not sure if Buddha was a god or not. Animists think your chair might be a god. Ancestor worship stoops even lower.
The God of the Bible is Jehovah. He revealed Himself more fully to Moses as I AM THAT I AM. No other god has a name like that! He is eternally and infinitely independent of all other beings and creatures. He alone is the supreme Being.
He looked for other gods, but He could not find any. He wanted to humiliate them by His superior wisdom and power. If you want to read about the LORD God Jehovah boasting, then read Isaiah chapters 40-49. Just make sure you trust Him!
The greatest proof of God’s existence and His power to perform is fulfilled prophecies. The gods of other religions have no such thing. If they claim prophecies for their gods, they were never fulfilled, and most are wise enough to
The God of the Bible loves to make fun of other gods and those that worship them (Ps 115:1-8; Is 44:9-20). You should enjoy making fun them as well, like Elijah (I Kgs 18:21-29). If you like dominating wins, Jehovah over other gods is dominating!
The Trinity does not change the fact there is only one God. There are not three Gods. There is only one God, but He exists by three Persons (Gen 1:1,26; Deut 6:4; Is 6:8; I John 5:7). There is only One Spirit, but seven manifestations (Rev 3:1; 4:5; 5:6).
God and Jesus are different. Jesus is not another God. Jesus is a Man (I Tim 2:15). Jesus is the fullness of God in a body (Col 2:9). Jesus is God made flesh to die for His people (Jn 1:14; Phil 2:5-11). Jesus is subordinate to God (I Cor 15:28).
