God is the only Infinite and Eternal Being – having no beginning and no end – the Creator and Sustainer of all things. 

The Bible nowhere attempts to prove or argue the existence of God.  God’s existence is a fact taken for granted by the writers of both the old and new testaments.

The Bible opens by announcing the sublime fact of God and His eternal existence – “In the beginning God,” Gen. 1:1 

• Universal belief in God comes from within mankind.  It is an innate belief, sourced from rational intuition.
• The cause and effect argument – Everything that began owes its existence to a cause – we have a watch – we must have a watchmaker.  The Creation could not have come into being without a creator, no more than a book can be produced from the alphabet without an author.
• Via anthropology – man’s moral and intellectual nature argues for a moral and intellectual creator.
• The Bible and the Christ it reveals – His Virgin birth, sinless life, vicarious death and bodily resurrection, and documented miracles – all argue for the existence of God. 

Man is natural and cannot know God by wisdom. The Bible argues for our faith in God – not His existence.  It says in multiple places that those who do not believe in the existence of God are fools, because He is so obvious. 

Job 11:7

King James Version (KJV)

Canst thou by searching find out God? canst thou find out the Almighty unto perfection?

Hebrews 11:6

King James Version (KJV)

But without faith it is impossible to please Him: for he that cometh to God must believe that He is, and that He is a rewarder of them that diligently seek Him.

The phrase highlighted in red above is pivotal. “he that cometh to God must believe that He is,” is imperative.  This is the free will that He gave to us – we must decide, and then choose Him.
