I think that if God forgives us we must forgive ourselves. Otherwise, it is almost like setting up ourselves as a higher tribunal than Him. - C. S. Lewis

This is the terrible fix we are in. If the universe is not governed by an absolute goodness, then all our efforts are in the long run hopeless. But if it is, then we are making ourselves enemies to that goodness every day, and are not in the least likely to do any better tomorrow, and so our case is hopeless again....God is the only comfort, He is also the supreme terror: the thing we most need and the thing we most want to hide from.

Humans are amphibians...half spirit and half animal...as spirits they belong to the eternal world, but as animals they inhabit time. This means that while their spirit can be directed to an eternal object, their bodies, passions, and imaginations are in continual change, for to be in time, means to change. Their nearest approach to constancy, therefore, is undulation — the repeated return to a level from which they repeatedly fall back, a series of troughs and peaks.

Aim at Heaven and you will get Earth 'thrown in': aim at Earth and you will get neither.
