Calling things that are not...Rom 4:17

(As it is written, I have made thee a father of many
nations,) before him whom he believed, even God, who
quickeneth the dead, and calleth those things which be
not as though they were.

Here God shows us how he had to call Abram
Abraham which means 'Father of Nations'
before he became a father of nations calling those things
which were not as though they were.

This is important in anything we need and ask God for. We
must talk, think and act like we have what we seek before we
receive it. That is faith in action.
