Proverbs 14:4 Without oxen a stable stays clean, but you need a strong ox for a large harvest.
I thought want on earth does this verse mean?!?!?! Then almost as quickly as I had that thought I had the answer. We can stay in our safe little world of home and church... surrounded by things that don't tempt us that don't dirty our minds ... that won't dirty our hearts... but to reach people for God we need to risk messing up... getting "dirty"... taking the wrong steps to reach thee people that don't know about God's great love. I think God would rather us try and mess up and learn and try again... than for us to stay as white as snow locked away from the world... when we take that step in faith God's grace steps in and takes over.
