This morning during "Morning Prayer" I read Genesis 15:1-6

I read the words, "...do not fear, Abram!  I am your shield; I will make your reward great."

Was this a one time promise specific to Abram, or is it for "all time and everyone"?

Could we put our names in place of "Abram"? 

I love that we are not to fear and the fact that the Lord IS OUR SHIELD and the thought of heaven as our reward...
