“If we rejoice with the world, there is reason to fear that with the world we shall grieve too. But when the world rejoices, let us grieve; and when the world afterward grieves, we shall rejoice.”

I Think I'll Sit This One Out (1939)
Context: It is a sensible military tactic to recognize the enemy before you shoot. The common enemy is the animality in man, and not the men here and there who are behaving like animals at the moment. Neither science nor prayer nor force will save us. What will save us is the reason that enables men, in ancient Israel and modern America, to choose between guns and butter, and to choose well. When we have produced men of reason, we shall have a world of reason, and the Hitlers will disappear. As long as we produce men of force we shall have a world of force, and the Hitlers, whoever wins the wars, will carry the day.
Society may make many demands on me, as long as it keeps me out of the cave. It may take my property. It may take my life. But when it puts me back into the cave I must say, politely but firmly, to hell with society. My ancestors were cannibals without benefit of parliaments.

Context: If you are a preacher of mercy, do not preach an imaginary but the true mercy. If the mercy is true, you must therefore bear the true, not an imaginary sin. God does not save those who are only imaginary sinners. Be a sinner, and let your sins be strong (sin boldly), but let your trust in Christ be stronger, and rejoice in Christ who is the victor over sin, death, and the world. We will commit sins while we are here, for this life is not a place where justice resides. We, however, says Peter (2. Peter 3:13) are looking forward to a new heaven and a new earth where justice will reign.
