If God forgives everything, does it matter what I do?

Why do we need forgiveness? Christians talk about ‘sin’, which is a bit of a confusing, old-fashioned word. It makes more sense if we look at its original meaning: the Greek word for ‘sin’ came from an archery term meaning ‘to miss the mark’. Sin isn’t just the obvious stuff like murder or stealing, it’s anything that ‘misses the mark’, that falls short of God’s perfect standard. A standard none of us can meet.
