Happiness is based on circumstantial pleasure, excitement, or something that causes one to feel hopeful for the moment. Joy does not depend on circumstances because we trust God’s character. Joy is unaffected by outward circumstances. In fact, it usually thrives best when times are tough! Joy can be defined as a sense of undisturbed peace, purpose, contentment, and well being with God; coupled with a positive expectation and anticipation of God's best for my life in every situation.
