It is ingrained in all living creatures, first of all, to preserve their own safety, to guard against what is harmful, to strive for what is advantageous.
AmbroseA good youth ought to have a fear of God, to be subject to his parents, to give honor to his elders, to preserve his purity; he ought not to despise humility, but should love forbearance and modesty. All these are an ornament to youthful years.
AmbroseIf you offer fasting with humility and with mercy, your bones, as Isaiah said, shall be fat, and you shall be like a well-watered garden (cf. Isa. 58:11). So, then, your soul shall grow fat and its virtues also by the spiritual richness of fasting, and your fruits shall be multiplied by the fertility of your mind, so that there may be in you the inebriation of soberness, like that cup of which the Prophet says: 'Your cup which inebriates, how excellent it is' (Ps. 23:5 LXX)!
AmbroseBlessed, plainly, is that life which is not valued at the estimation of outsiders, but is known, as judge of itself, by its own inner feelings. It needs no popular opinions as its reward in any way; nor has it any fear of punishments. Thus the less it strives for glory, the more it rises above it. For to those who seek for glory, that reward in the shape of present things is but a shadow of future ones, and is a hindrance to eternal life, as it is written in the Scriptures: 'Truly I say to you, they have received their reward'
