As you get ready to speak on any upcoming retreat, I’d encourage you to keep in mind that your talk is the most important talk of the retreat – for at least one person who will be there (and possibly for many others).
If this thought makes you a bit nervous, that’s not a bad thing. As my father-in-law used to say to me, when I asked him for prayers for an upcoming talk, “If you weren’t nervous, I would be.” Being somewhat nervous is a good thing; it’s a sign of humility and an expression of our awareness that we desperately need God’s help, since without Him we can do nothing (John 15:5).
The Lord has you going on this retreat for a specific reason. You have something unique to offer that only you can bring, and at least one person desperately needs to hear what you have to say.
