Who is GOD?
God exists. He is beyond the universe, he is everything. He is infinite. God is in and outside of TIME, SPACE, MATTER, FORCE and DIMENSIONS. Beyond positive or negative.
Did man know immediately that God exists? No! Man needed to experience God. Man needed to experience God's creation to realize that God exists. Humanity's perception of God came in many ways.
Our emotions (positive and negative) not our intelligence made us first realize that there is God. The experiences of joy, happiness, laughter, prosperity, relaxation, bravery, love, compassion, kindness, sadness, anger, loss, anxiety, stress, fear, yearning, guilt, greed, deprivation, vanity and hate helped us to be aware of someone superior to humans. These experiences made humans realize that there's something or someone out there that is beyond the powers of humans. When an individual accomplishes something that is beyond his personal capacity as he knows it, he then realizes a power from beyond has helped him.
When we see others suffer, we feel compassion. We get this sympathetic pity and concern for the sufferings or misfortunes of others. The instinctive kindness and mercy pours out from our hearts.
Since time immemorial, man accepted God and also denied the existence of God. There are more who accept vs those who reject. The common denominator in most of those who reject God is that they have accepted God before then somehow because of deprivation, selfishness, vanity or confusion, they have concluded that God does not exist.
Even atheist believe in love, yet they can't explain love. Love is not a simple reaction. Love transcends. Atheists believe in this but can't explain it. Yet they conveniently deny God. Every single one of them maintain the DENIAL LOGIC.
Many books were and are still being written about the non-existence of God and some of the authors became famous specially in the atheistic realm. These books were written based on the writings of religions. To them religion is the foundation of God. Wrong! God is the foundation of religions. Religions were invented by inspired humans for humans to belong to a group, to a community where they can share the same concept of loving and sharing, the same concept of who the supreme being (God) is.
