“Oh, the bravery of God in trusting us!” —Oswald Chambers  He goes on to say this–

It is not a matter of our equipment, but a matter of our poverty; not of what we bring with us, but of what God puts into us; not a matter of natural virtues, of strength of character, of knowledge, or of experience–all of that is of no avail in this concern.  The only thing of value is being taken into the compelling purpose of God and being made His friends (see 1 Corinthians 1:26-31).

Keep your goodness and agenda out of it–blessed are the poor in spirit.

In other words, being useful to God is useless.  Be His friend ;-).
