The birth, death, and resurrection of Jesus means that one day everything sad will come untrue.
Living by faith includes the call to something greater than cowardly self-preservation.
All we have to decide is what to do with the time that is given us.
How do you move on? You move on when your heart finally understands that there is no turning back.
The chief purpose of life, for any of us, is to increase according to our capacity our knowledge of God by all means we have, and to be moved by it to praise and thanks.
