Unbelief is as much of a choice as belief is. What makes it in many ways more appealing is that whereas to believe in something requires some measure… - Frederick Buechner

If we are to believe he is really alive with all that that implies, then we have to believe without proof. And of course that is the only way it could be. If it could be somehow proved, then we would have no choice but to believe. We would lose our freedom not to believe. And in the very moment that we lost that freedom, we would cease to be human beings. Our love of God would have been forced upon us, and love that is forced is of course not love at all. Love must be freely given. Love must live in the freedom not to love; it must take risks. Love must be prepared to suffer even as Jesus on the Cross suffered, and part of that suffering is doubt.

Principles are what people have instead of God.
To be a Christian means among other things to be willing if necessary to sacrifice even your highest principles for God's or your neighbour's sake the way a Christian pacifist must be willing to pick up a baseball bat if there's no other way to stop a man from savagely beating a child.
Jesus didn't forgive his executioners on principle but because in some unimaginable way he was able to love them.
'Principle' is an even duller word than 'Religion'.

The time is ripe for looking back over the day, the week, the year, and trying to figure out where we have come from and where we are going to, for sifting through the things we have done and the things we have left undone for a clue to who we are and who, for better or worse, we are becoming. But again and again we avoid the long thoughts….We cling to the present out of wariness of the past. And why not, after all? We get confused. We need such escape as we can find. But there is a deeper need yet, I think, and that is the need — not all the time, surely, but from time to time — to enter that still room within us all where the past lives on as a part of the present, where the dead are alive again, where we are most alive ourselves to turnings and to where our journeys have brought us. The name of the room is Remember — the room where with patience, with charity, with quietness of heart, we remember consciously to remember the lives we have lived.
