Today in my daily reading, one of the verses I came across was Isaiah 6:8
Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me.
and I just wanted to post a quick thought.
I wonder what this world would be like if all Christians were this eager to be used by God at His calling. I once heard a saying that the only ability God cares about is availability. Let's be available, willing, eager.
