What I absolutely want is to suggest that before it's anything else, redemption is God mending the bicycle of our souls; God bringing out the puncture repair kit, re-inflating the tires, taking off the rust, making us roadworthy once more. Not so that we can take flight into ecstasy, but so that we can do the next needful mile of our lives.
For a believer, Christian faith is true to the human heart, not in the sense that any old thing we fancy believing in will become conveniently true - but because the complicated truth about our hearts, as we struggle to perceive it, tells us what we are and where we are, and consequently what we need.
Christians are as subject to complacency as anybody else, and we can certainly settle into repetition and forget that something radical and extraordinary is being asked of us as well - that we hold to an extraordinary promise about how, from moment to moment, something enters the world and enters us, after which everything is different.
If you're a believer, God is not a thought-experiment requiring a special sub-creation to be tried out in. He's an actual, er, actuality already, embedded in a necessary and true story about guilt, hope, and liberty. I don't want C. S. Lewis doing his resourceful best to render Him as a fabulous special effect.
I think I have made allowances for the kind of despair which would test my faith, but you cannot know in advance what disaster to those you love would be too much to bear faithfully, and like everyone's, my faith is weakly conditional in some ways. I hope, I pray not to lose it. My fingers are crossed. Also my heart.
Christianity is a religion of continuity and discontinuity as well. It's about what stays the same and what changes in the twinkling of an eye. Both are necessary truths, but sometimes it's important to accentuate the discontinuity, the sudden leap, the way you go up a tree, Zacchaeus, and come down a saint.
Emotions can certainly be misleading: they can fool you into believing stuff that is definitely, demonstrably untrue. Yet emotions are also our indispensable tool for navigating, for feeling our way through, the much larger domain of stuff that isn't susceptible to proof or disproof, that isn't checkable against the physical universe.
