Now, some translations are going to say "deeds." We've talked about this once or twice before. The NIV, in particular, is very suspicious towards the English word "works." This is basically a strain of anti-Catholic thought that shows up in Protestant Bibles — because Protestants, well, we don't believe in works; we believe in faith alone. But the same word that gets translated as "works" is used here, and Jesus is saying it in a positive sense. "I know your works" — this is a good thing.
