“For a man to be proud of his riches, is as if a horse was proud of his trappings. Your riches are but thorns which, without great care, will penetrate your hands. Many names are given in Scripture to riches, to wean us from them, such as mammon of unrighteousness, riches that fly away and deceitful riches…O Christian, never be proud of things that are so transient, injurious, and uncertain as the riches of this evil world, but set your heart on the true and durable riches of grace in Christ Jesus.”
Isaac Ambrose (1604-1664) in The Christian Warrior (Westfield, Digital Puritan Press, 2013) 82, originally published in 1674 as War with Devils.
