Perhaps you should try some spelling variations:
2f sermons » 2 sermons, 24 sermons, 20 sermons
2f matthew » 2 matthew, 22 matthew, 25 matthew
21 sermons » 2 sermons, 1 sermons, 6 sermons
2f early » 24 early, 20 early, 22 early
21 early » 2.1 early, 1 early, 11 early
c 51 » c 5, _ 51, c 11

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22bible %2f n.t %2f matthew xxv%((c 51) OR (c 1)) %((2f sermons) OR (21 sermons)) %((2f early) OR (21 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22bible %2f n.t %2f matthew xxv%((c 51) OR (c 1)) %((2f sermons) or (21 sermons)) %((2f early) or (21 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %22bible %2f n.t %2f matthew xxv%((c 51) OR (c 1)) %((2f sermons) or (21 sermons)) %((2f early) or (21 early)) works to 1800%22*.
