I'm saddened over the fact that I've said many wrong things in the midst of preaching. I don't believe I've made any weighty theological errors, but sometimes I later learn in my study that something I said in a sermon was wrong. For example, last week I mentioned that after the flood, God said that the number of days of man would be 80 years (I was going from memory, but I was confident of the number, so I said it). But looking up today, I see that I was wrong about the number. It was 120 years. I confused the verse with Psalm 90:10, which says that the years of our lives are seventy, or eighty if we have the strength. That's the only example I can think of right now, but I know that I make these kinds of mistakes from time to time. I do a lot of fact checking before preaching, but sometimes I think I remember something while preaching that adds to the point, and while I usually have my facts straight even in these, sometimes I don't. Should I just stick to my notes? Does this happen to you? What do you do when you've made this kind of mistake?
