I am old enough to recall the lives of the many deceased relatives and friends of mine. Like most lives, they had happy times as well as sad ones. All I can say is that if we only seek happiness but do not have Christ, then we are merely going through the motion. It is the Lord who can give us the right perspective on life, giving it meaning and direction. Living for God frees us from the prison of living for ourselves. It's living a new life not bound by this world.
