NOTHING you do is so small that God cannot use it.
I'm always so surprised that God chooses to use things that I say or do that seem random and not all that well thought-out. But God is GOD. He can elevate the simplest thoughts to be exactly the words that someone needs to hear. He can use our words... and apparently pictures to impact others. Afterall, everyone has their own learning-style (as we like to say around here), and different things speak to different people.

What a mighty God I serve!
I need to remember not to underestimate how he can use me.
