Dietrich Bonhoeffer

[The unchristian environment] is the place where we find out whether the Christian’s meditation has led him into the unreal, from which he awakens in terror when he returns to the workaday world, or whether it has led him into a real contact with God, from which he emerges strengthened and purified. Has it transported him for a moment into a spiritual ecstasy that vanishes when everyday life returns, or has it lodged the Word of God so securely and deeply in his heart that it holds and fortifies him, impelling him to active love, to obedience, to good works? Only the day can decide.
