The world around us is filled with vanity. Looking for the meaning of life, through life, is vanity. Looking for the meaning of life through God, the creator of all life, is our duty as Christians. God wants us to live our life with the purpose He has given us. Through spiritual understanding of God's plan, and our commitment to His commandments, we will be set us apart from the world. Our righteousness will cause us to stand out. This is not vanity.
