Martin Luther wrote the following to his barber when asked for advise on how he should pray.
So a good and attentive barber keeps his thoughts, attention, and eyes on the razor and hair and does not forget how far he has gotten with his shaving or cutting. If he wants to engage in too much conversation or let his mind wander or look somewhere else, he is likely to cut his customer’s mouth, nose, or even his throat. Thus if anything is to be done well, it requires the full attention of all one’s senses and members, as the proverb says, “The one who thinks of many things, thinks of nothing and does nothing right.” How much more does prayer call for concentration and singleness of heart if it is to be a good prayer!
“A Christian fellowship lives and exists by the intercession of its members for one another, or it collapses. I can no longer condemn or hate a brother for whom I pray, no matter how much trouble he causes me. His face, that hitherto may have been strange and intolerable to me, is transformed in intercession into the countenance of a brother for whom Christ died, the face of a forgiven sinner. This is a happy discovery for the Christian who begins to pray for others.” – Dietrich Bonhoeffer in Life Together
It makes me think of why Christians fight so much, and I cannot help but think that Bonhoeffer is onto something. How would our fellowship with other believers (both those in our church and in the broader Christian community) be changed if we prayed for each other more?
