All people must believe in God. We all must believe in God. There should not be people who do not believe in God. Every person should believe in God. They must all believe in God. God gives us the mentality to believe in him all people must believe in God.
God is the one who created us. Every one was created by God, so everyone should believe in God. That mind with which we believe things came from God. We cannot reject the very God who created us. He is the one who created us. So there is no reason for doubting the existence of God. Let everyone of us believe in God and obey His commandments.
Every person who refuses to believe in God is not using his mind rightly. Every right thinking person will believe in God. How could the existence of God be question when we see such a beautiful world like this. Who created all these wonderful creatures which are existing? It is God who created everything.
