Genesis 18 part 1 Are you ready for a visit from GOD?

The first 15 verses are very interesting here.  Abraham has these visitors and how this old man runs to greet them and take care of them shows us for sure who this is.  
Interesting side note, i will talk about tomorrow if i remember... the word "hard" is the same Hebrew word used in Isaiah 9:6 when talking of the coming messiah, translated into English as "Wonderful".
