Happiness can be elusive.  We try to find happiness in achievement, relationships, things and nothing truly satisfies our longing.  Jesus in the introduction his most famous sermon recorded in the gospel of Matthew addresses our desire for real happiness.  Real happiness is found in the kingdom of God.  Jesus taught us how to enter the kingdom of God by being poor in spirit, mourning, being found to be meek and hungering and thirsting after righteousness.  Do you want to be happy?
Happy are you if you enter the Kingdom of Heaven through Jesus.
