Barry Maxwell has written a great post on pastoral ministry, especially from the perspective of analyzing on Monday what you just did on Sunday. He entitled it “Another Monday Reflection” and it is essentially a meditation on Rom 15:15-16.
While you are at it check out his honest Monday lament, “Another Manic Monday.” (Once you take this link you will have to scroll down to find this entry). It is a good example of being honest about the weightiness of the task. This sort of honest wrestling leads to the confidence in God discussed in “Another Monday Reflection”.
Thanks for sharing both your doubts (of self) and discoveries (of God), Barry.
