Many people didn't believe in the existence of God, Why didn't believe in the existence of God ? because their mind are not able to find out God (in their mind). God cannot be found with the mind, but can be believe with IMAN (the heart). Talking about "Looking for God..?" There is an interesting story in the Quran. Please open the 6th Surah of the Quran, Surah Al-Anam, verse 76 until 79. The story Prophet Ibrahim looking for God.
V.76. When the night covered him over with darkness he saw a star (Ibrahim saw a star) He said " This is My Lord", But when it set. I like not those that set. I like not those star, that set. V.77. When he saw the moon rising up, (Ibrahim saw the moon rising up), He said : " This is my Lord" But when it set, He said :" Unless my Lord guides me , I shall surely be among the erring people".
V.78. When he saw the sun rising up (Ibrahim saw the sun rising up), He said , "This is my Lord. This is greater". But when it set, he said " O my people I am indeed free from all that you join as partners in worship with Allah". Millennials. who are loved by Allah.... Finally, Prophet Ibrahim found Allah, that Allah who created the stars, the moon and the sun. The stars, the moon and the sun were created by Allah, the heavens and the earth were created by Allah. V.79. Verily, I have turned my face towards Him Who has created the heavens and the earth Hanifan (Islamic Monotheism, i.e. worshipping none but Allah Alone), and I am not of Al-Mushrikun (those who worship others besides Allah). Everything comes from Allah so follow it, and please accept it. I would like to ask your apologize for my mistake and weaknesses. Wallahu 'alam Bish-Shawab.
