Preparation for the Day of Judgment
So, then, brethren, having received no small occasion to repent, while we have opportunity, let us turn to God who called us, while yet we have One to receive us. For if we renounce these indulgences and conquer the soul by not fulfilling its wicked desires, we shall be partakers of the mercy of Jesus. Know that the day of judgment draws near like a burning oven, and certain of the heavens and all the earth will melt, like lead melting in fire; and then will appear the hidden and manifest deeds of men. Good, then, is alms as repentance from sin; better is fasting than prayer, and alms than both; “charity covers a multitude of sins,” and prayer out of a good conscience delivers from death. Blessed is every one that shall be found complete in these; for alms lightens the burden of sin.
