What is necessary for life? Certainly air, water, and food are essential to sustain physical life. Along with rest and exercise, these keep the body moving, but life is more than the physical body. We need a reason for being. Animals survive by nature and instinct, but humans ponder the question of purpose. Why am I here? To answer this, we need fellowship with other humans to give us a sense of belonging, and we need faith to show us that there is something beyond our brief span of years. We are not self made, and we are not self sufficient. Our God, the Father of our Lord Jesus Christ, invites us to find our meaning in Him. There are many world faiths. This shows the hunger in man for meaning. But true meaning is only found in the One who loved us enough to reveal Himself personally in Jesus Christ. That is what Christmas is about. By growing deeper in our life with Jesus we find meaning for life. And that is more necessary than just sustaining physical life.
