One cool thing about the 21x21 Bible puzzles is that you do not need access to a Bible to solve the puzzle. Most clues have a '?' symbol to the right of the clue. Clicking the '?' symbol will take the solver to a page where the Bible verse can be read to find the answer.
I also tried to include an alternative clue for each word that is a common everyday word. Example, for the answer SLEEPER, I have this clue:
Train car or person who needs awoken in Ephesians 5:14 (NIV)
Note: There is also a PDF version of the puzzle that can be displayed by clicking the PDF link.
