Whose creation is this universe? How did all its systems come into being? Everything lives within its limits. Surely there is an entity that is running this system. Isn't man a masterpiece? Is there not a soul that makes this body? All this did not happen by itself. The answer is no. All this has happened on a complete plan under a complete system. Some people understand this and those who don't, if they think about their surroundings, they will surely understand.
We did not come into this world without a reason. Our Lord has sent us to this world to test us to decide heaven and hell. This world is temporary, real life will begin after death. Who does not fall.
