For things to exist, there must be beginnings. In fact, since nothing can possibly pop out of nothing to exist as something, there has to be the existence of something or someone who has always existed, for whom there is no beginning ~ and that is God our creator. If God has no beginning, then there will be no end for him either ~ so he is everlasting. In John 8:58, Jesus said, "Amen, amen, I say to you, before Abraham came to be, I AM" ~ he said it all. Therefore, there are no longer any mysteries about the universe and us. Furthermore, the greatest mystery, the Lord himself, has been revealed to us through the Old Testament prophets and in particular, his own beloved Son Jesus.
