Human beings have been equipped with all the systems they need within this extraordinary environment. The more details that we learn about the body, the more we realize how miraculous our lives are. As they discover the systems concealed inside their bodies, many people- -who would otherwise live without reflection, caught up in the daily course of their lives--will reflect on the purpose behind their existence and become aware of their responsibilities to Allah, their Creator.
Indeed, various scientists have acquired faith in the existence of Allah by seeing the greatness of His knowledge and the perfections He has created. But some of them continue to refuse to see that they live in need of Allah, even though their consciences may tell them otherwise. Yet their refusal to admit the truth will not alter the facts. Allah reveals some people's approach in the Qur'an:
Do not mix up truth with falsehood and knowingly hide the truth. (Su- rat al-Baqara, 42) O Humanity! You are the poor in need of Allah whereas Allah is the Rich Beyond Need, the Praiseworthy. (Surah Fatir, 15)
