WHO IS GOD..according to the Bible ?

WHO IS GOD , according to the Bible ? Which is God's message to man ....for all ages past , present and future .
The book of Genesis was originally written in Hebrew .And in the first verse of the Bible we read . GENESIS 1:1 "In the beginning God created the Heavens and the Earth ." The word for God used here is ‘Elohim...’ in Hebrew . The word ‘Elohim’ is used whenever the power of God is revealed . And here we are reading about the creative power of God .Therefore, it was "Elohim" who spoke the universe into existence. This name is very special when considering who God is. It is a plural word, which means ‘more than one.’ It is significant because it speaks to of the Godhead (Trinity is a uni-plural word rather than the idea of three Gods) – Father, Son and Holy Spirit. Genesis chapter one tells us that the Godhead was involved in Creation, but the rest of the Bible reveals what each Person was doing.
