Christianity is not simply a collection of truths to be believed. Nor is it all about how a person can get to heaven after they die. Instead, Christianity is a whole new way of living that is at odds with the way of the world. Right at the centre of this new life is the cross and resurrection of Jesus. Just as Jesus willingly humbled himself so God might receive glory, we are to follow after him with this same mindset. Only in this way will we have true joy.
