“Every creature is better alive than dead, men and moose and pine trees, and he who understands it aright will rather preserve its life than destroy it.”

Discipleship (1937)
Context: Should the church be trying to erect a spiritual reign of terror over people by threatening earthly and eternal punishment on its own authority and commanding everything a person must believe and do to be saved? Should the church's word bring new tyranny and violent abuse to human souls? It may be that some people yearn for such servitude. But could the church ever serve such a longing?
When holy scripture speaks of following Jesus, it proclaims that people are free from all human rules, from everything which presumes, burdens, or causes worry and torment of conscience. In following Jesus, people are released from the hard yoke of their own laws to be under the gentle yoke of Jesus Christ. … Jesus' commandment never wishes to destroy life, but rather to preserve, strengthen, and heal life.

Context: War is an ugly thing, but not the ugliest of things: the decayed and degraded state of moral and patriotic feeling which thinks that nothing is worth a war, is much worse. When a people are used as mere human instruments for firing cannon or thrusting bayonets, in the service and for the selfish purposes of a master, such war degrades a people. A war to protect other human beings against tyrannical injustice; a war to give victory to their own ideas of right and good, and which is their own war, carried on for an honest purpose by their free choice, — is often the means of their regeneration. A man who has nothing which he is willing to fight for, nothing which he cares more about than he does about his personal safety, is a miserable creature who has no chance of being free, unless made and kept so by the exertions of better men than himself. As long as justice and injustice have not terminated their ever-renewing fight for ascendancy in the affairs of mankind, human beings must be willing, when need is, to do battle for the one against the other.
