"As we are strangers, sojourners, and travellers to the heavenly kingdom, we must not burden ourselves with worldly cares, nor become attached to earthly blessings, riches, pleasures, honours, in order that these cares and attachments should not hinder us in the hour of death, nor make it shameful. The Christian, even here on earth, must accustom himself to live the heavenly life; in fasting, in renunciation, in prayer, love, meekness, gentleness, patience, courage, and mercy. How hard will the hour of death be to the man who in his lifetime made his idols of money, or food, and drink, or earthly honours! In that hour none of these things shall serve him, whilst his heart, being strongly attached to them, does not possess the true treasure, which would give him life, that is, virtue. And therefore, in order to die more easily -- and we must all die -- we must not love anything in the world. 'And having food and raiment, let us be therewith content' (1 Timothy 6:8)."
