Faith and Nothingness

"God..calls things that are not as though they were." (Rom 4:17)
-----------------------------------------------
Emptiness, the seeming void around;
Frustration of silent blankness;
Impatience, the restless hunger inside;
Darkness, the unknown nothingness;
Faith that triumphs over all, for it calls
Things that are not as if they are.

Calls those things which do not exist as though they did (Rom.4:17)

Calls those things which do not exist as though they did (Rom.4:17)
...
I find this puzzling aspect of faith. To call things that aren't as though they are.

Not.. I will make you.. But, I have made you a father of many nations......
