Three Wishes (Miracle): An Aptly Named Sudoku

Today's Puzzle:

I haven't come across Matt Tressel before, admittedly all his puzzles other than this one are 3 and 4* difficulties, so understandable, but he's put out a miracle of a Sudoku that I am delighted to play and feature.

Take the time to solve this one and enjoy!
