Many people today are easily influenced by what's happening around them. They are happy one minute, but the moment someone says something they don't like, or traffic hits, or a grouchy boss or family member says something, they're offended and upset.
But Jesus said in John 14:1, "Stop allowing yourself to be upset." Let Joel teach you how to live life deeper to where you're unmoved by external things. Life is too short to let your circumstances determine your joy. Start enjoying your life more and live with greater levels of peace and joy as you grow your roots deeper!
