People should believe in God. Not that some people believe and some don't, not all people believe in God but the case must be that all people must believe in God, because we are all created by God. Humans are created by God, we do not exist by ourselves alone, so every human being having the mentality given by God more than the mentality of other animals, must believe in the one true God.
There are people who do not believe in God and the Bible tells us so, what kind of people are those who do not believe in God
Psalms 53:1:
The fool hath said in his heart, There is no God. Corrupt are they, and have done abominable iniquity: there is none that doeth good.
According to the Bible, those who are called by God as fools, are those that do not believe in God. So, it is Biblical to say that those who do not believe in God are fools, they are people without understanding, those who do not believe in God are people who are not using their minds to think that, there must be somebody who created us.
If you study the wonders of the human body, the human mind, the human eyes, the human brain, you will come to know that our being is designed by a very intelligent Creator, the human mind is more sophisticated than any computer that is now existing on Earth. If you accept the fact that computers were made by man, you must also accept the fact that the human brain did not just happen to be like that—it was created and designed by an intelligent Creator and the Bible calls Him, God.
God is the creator of everything that exists, so people must believe im God if we are using our brains, why? Because if you understand the functions of the human body in its entirety, you will not believe that no one created us.
We do not exist by accident, there is a superior being who created us. His creation reveals that He is Almighty and He is powerful.
