When Thomas Watson tells Christians to enact “holy violence,” he’s not talking about physical warfare. He’s urging Christians to take up spiritual arms in their pursuit of righteousness. Watson, a Puritan preacher and writer, uses passionate language to capture the fervor with which Christians should perform their duties of prayer, Bible-reading, meditation, and more. This fiery text is perfect for anyone looking to reignite their spiritual life so they can, as Watson puts it, “take Heaven by storm” and fight against evil.
