"Why is it that my thoughts depart so quickly from God's Word and I find the necessary word is often not there for me in the hour of need? Do I forget to eat and drink and sleep? Why do I forget God's Word? Because I am not yet able to say with the psalmist: 'My delight is in your statutes.' I never forget that in which I delight. To forget or not is a matter not only of the mind but of the whole person, including the heart. That on which my life and soul depend I cannot forget. The more I begin to live the ordinances of God in creation and in his Word, the more they will be present for me at every hour. Only love guards against forgetting."
Dietrich Bonhoeffer, No Greater Love: Lenten Meditations
