This sermon did not feel as good as I anticipated it would in the preaching. I think it's because, in the presence of the congregation, I became very aware of the content seeming to imply that I agree with the notion found in scripture and in the biblical cultural context, that children are a blessing from God, and lack of children are a sign of God's disfavor. In a sermon like this, when you are trying to give the feel of a character (fictional,of course, only based on some bare bones facts found in scripture), you can put words in his mouth that you really don't embrace as part of your belief system. In this case, I certainly don't believe that those who are not able to give birth are in any way "lacking," or are not blessed by God (though I know it might be tempting in that situation to feel that way).
So, as I preached, I fretted over the possibility that there might be childless folks in the congregation who might think that's what I believe, or how I think God works. So I ended up doing some improvising that probably weakened the sermon.
Grrrr. Hate that feeling: what if the words I'm preaching hurt someone?
