Why Does God Need Validation
It is our moral and ethical being that requires us to recognize and acknowledge the greatness of God. Ungratefulness is impurity, and God wants us to be pure, so that He may reward us for our little effort with eternal blessings which are for those only who would purify themselves. God says in the Quran يَا أَيُّهَا النَّاسُ أَنتُمُ الْفُقَرَاءُ إِلَى اللَّهِ ۖ وَاللَّهُ هُوَ الْغَنِيُّ الْحَمِيدُ ‎﴿١٥﴾‏ إِن يَشَأْ يُذْهِبْكُمْ وَيَأْتِ بِخَلْقٍ جَدِيدٍ ‎﴿١٦﴾‏ وَمَا ذَٰلِكَ عَلَى اللَّهِ بِعَزِيزٍ O people, it is you who stand in need of Allah; as for Allah, He is Self-Sufficient, Immensely Praiseworthy. (15) If He wishes, He can remove you and put in your place a new creation. (16) That surely is not difficult for Allah.
