Who is God?

God, after He spoke long ago to the fathers in the prophets in many portions and in many ways,
 in these last days has spoken to us in His Son, whom He appointed heir of all things, through whom also He made the world.
 And He is the radiance of His glory and the exact representation of His nature, and upholds all things by the word of His power When He had made purification of sins, He sat down at the right hand of the Majesty on high, having become as much better than the angels, as He has inherited a more excellent name than they.
 
The above verse tells us that God has spoken to us. 
What are two ways He has spoken to us?

App War

There is a war over words happening out there.  iPhone and Android apps are being used to buttress their points of view when debating the God vs no God topic.  If you believe God is all-powerful, and all-knowing, and you want to defend your claim, then there is an app for that.   If you know for sure God is imaginary, then you have apps to back you up.
