Monotheism is the belief that there is only one God in charge of the world and nothing else. Biblical monotheism is a belief in a Godhead, often called the Trinity, that exists in the persons of the Father, Son, and Holy Spirit. This Godhead is described as the three in one.
That is it. That is all that Christians believe.
This conviction also means there are a large number of things they do not believe. They do not believe in luck. Personally, I have spent the past few years trying to eliminate the word from my vocabulary as I hear it used dozens of times a day, and I simply don’t believe it exists.
The list could go on and on. Christians don’t believe in luck, karma, superstitions. Neither do they believe in palm readers, psychics, Ouija boards, voodoo, reading tea leaves, bent spoons, ghosts, or fortune-tellers. They don’t throw salt over their shoulder, knock on wood or use dream catchers. They do not carry a rabbit’s foot, four-leaf clovers, or horseshoes for good fortune. They realize there are no such things as magic, horoscopes, astrology, wizards, or spells that can change people’s fate. There is a long, long list of things of which the followers of God do not believe.
I often think how crazy the people in the Old Testament were for trusting wooden and stone idols. They made them and then bowed down to worship them shortly after it was created. Are people today that far removed? We think an item we bought or an object we found somehow changes the outcome of games or brings good fortune. Believers today are called to push back from the belief in other powers the same as the people did in the Old Testament; just today, it wears different names.
