The world can be a conniving place; everyone looking out for their own interests, never looking forward to the final end but always looking at the here and now.
As followers of Jesus, our ultimate goal is heaven. Nothing else matters. To depend on this passing world is fruitless unless it leads us directly to our goal. The Gospels will always remind us of what is really important; that we see the face of Jesus in others. And, sometimes, when we start again to believe only in ourselves and our own self-interests, Jesus will stun us back to the reality of what it means to live our life in God.
