Our prayers for others flow more easily than those we offer on our own behalf. And it would be nice to accept your view that this just shows we are made to live by charity. I’m afraid, however, I detect two much less attractive reasons for the ease of my own intercessory prayers. One is that I am often, I believe, praying for others when I should be doing things for them. It’s so much easier to pray for a bore than to go and see him. And the other is like unto it. Suppose I pray that you may be given grace to withstand your besetting sin (short list of candidates for this post will be forwarded on demand). Well, all the work has to be done by God and you. If I pray against my own besetting sin there will be work for me. One sometimes fights shy of admitting an act to be a sin for this very reason.
