Philo Judaeus De Migratione Abrahami 123

[123] For even the slightest spark of fire that is still smouldering, when it is fanned and re-kindled will set fire to a large pile: and so too the smallest spark of virtue, when it beams up, being wakened into life by good hopes, gives light to what has previously been dim-sighted and blind, and causes what has been withered to shoot up again, and whatever is barren and unproductive it transforms and brings to abundance of prolific power. Thus a good, which is but rare, is, by the kindness of God, made abundant and showered upon men, making everything else to resemble itself.
