There are many things in life you can be known by, choose to be known by the boldness of your faith. Be willing to stand firm in a confidence in Jesus that doesn't make sense to the world around you. When Jesus calls you to walk on water, take the step. When doubt and fear begin to cause you to sink, look to Jesus. His hand is reaching out and ready to rescue you. Follow His voice, it will be worth whatever you have to surrender.
