Since I see so many people I know not living a joyful (not even happy) life, I'd like to draw the contrast between those who know God (Jesus) and those who do not. Those who have no faith seem to drift from day to day. They don't think about God (even though I believe that deep down they know that they should). They feel uncomfortable anytime God is mentioned (an indication that they really need him). Life is not fulfilling, at best OK. They worry about and plan for this life, avoiding thinking about life after death (out of fear?). They may seem cheerful on the outside, but they feel empty on the inside. Basically, they live a life of running away from life. Then those who have faith live exactly the opposite.
