We realize that no family can function properly without a responsible head, that no city can prosperously exist without sound administration, and that no state can survive without a leader of some kind. We also realize that nothing comes into being on its own. Moreover, we observe that the universe exists and functions in the most orderly manner, and that it has survived for hundreds of thousands of years. Can we, then, say that all this is accidental and haphazard? Can we attribute the existence of man and the whole world to mere chance.
In the world then there must be a Great Force in action to keep everything in order. In the beautiful nature there must be a Great Creator who creates the most charming pieces of art and produces everything for a special purpose in life. The deeply enlightened people recognize this creator and call him Allah 'God'. He is not human because no human can create or make another human. He is not an animal nor is He a plant. He is neither an idol nor is He a statue of any kind because none of these things can make itself or create anything else. He is different from all of these things, because He is the maker and keeper of them all. The maker of anything must be different from and greater than the things which he makes.
Scientists, even though they are able to reproduce human and animal life through artificial processes like in-vitro fertilization and cloning, cannot accomplish these feats without the basic elements of human life that consist of genes and cells and other organic properties. Scientists are not able to create these things. Even the processes that are used by scientists to accomplish various procedures originated from a source whose intellect was obviously far greater than those who seek to discover and imitate the creative processes.
Man cannot attain to his true humanity and acquire peace of mind unless he realises this aim for which he was created. But how can he do this! God, being merciful and Just, has helped him in many ways. He granted him an originally good nature that is inclined to know and serve its true Lord. He granted him a mind that possesses a moral sense and the ability to reason. He made the whole universe a natural book full of signs that lead a thinking person to God. But to make things more specific, to give him more detailed knowledge of his Lord, and to show him in a more detailed manner how to serve Him, God has been sending down verbal messages through His prophets chosen from among men, ever since the creation of man. Hence the description of these messages in the Qur'an as guidance, light, signs, reminders, etc.
How do you disbelieve in God(THE CREATOR), seeing that you were dead and He gave you life! Then He will cause you to die, then He will give you life, then unto Him you will return." [Al Qur'an (2:28)]
. How do you deny the Cause of your existence? It is like a machine denying the existence of its maker and not obeying his or her commands
The Atheist position is indeed hopeless. The believer has hope. If there is a God and there is life after death then the believer wins. If there is no God or no life after death the believer loses nothing. On the other hand, the Atheist loses badly if he wakes up to discover himself in the afterlife. In sum, if there is no afterlife both the believer and the Atheist are safe. But if there is an afterlife then the Atheist loses. The only one who can possibly lose is the Atheist.
On the other hand, it is the Atheist who is wasting his life. His life has no purpose but temporary enjoyment. But such enjoyment is always tempered by nagging doubts about whether or not life is heading in the right direction. It is the believer who lives in quiet confidence that God's promise is true.
