_she had nothing to do but to forgive herself and be happier than ever_

Progress in evil was quick and easy; Apollyon was not a chap who hid himself and he gave every assistance in his power. The growth in goodness was so slow, at times so flat, so dull, and like the White Queen one had to run so fast to stay where one was, let alone progress; and there were few men who dared to say they had found God. It was easy to be a clever sinner, for the race to an earthly visible goal was short to run, so impossibly hard to be a wise saint, with the goal set at so vast a distance from this world and clouded with such uncertainty.

I think you are falling into the very general error of confining the spiritual world to the supremely good; but the supremely wicked, necessarily, have their portion in it. The merely carnal, sensual man can no more be a great sinner than he can be a great saint. Most of us are just indifferent, mixed-up creatures; we muddle through the world without realizing the meaning and the inner sense of things, and consequently, our wickedness and our goodness are alike second-rate, unimportant.

Do not be devilish.

Don't make a deal with the devil.

Reject evil. Choose the good.
