We must recognise that duty and morality vary under different circumstances; not that the man who resists evil is doing what is always and in itself wrong, but that in the different circumstances in which he is placed it may become even his duty to resist evil.
In what way, or by what manner of working, God changes a soul from evil to good, how He impregnates the barren rock--the priceless gems and gold--is to the human mind an impenetrable mystery, in all cases alike.
When anything is in the presence of evil, but is not as yet evil, the presence of good arouses the desire of good in that thing; but the presence of evil, which makes a thing evil, takes away the desire and friendship of the good; for that which was once both good and evil has now become evil only, and the good has no friendship with evil.
Sense of pleasure we may well
Spare out of life perhaps, and not repine,
But live content, which is the calmest life;
But pain is perfect misery, the worst
Of evils, and excessive, overturns
All patience.
