Death Rhymes With a Puzzle In It.

NIGHT AFTER NIGHT, DAY AFTER DAY
ON WEEKLY SERMON TO YOUR MIDNIGHT PRAY.
OVER YOUR SHOULDER, YOU FEEL LIKE SOMEONE'S WATCHING
NOT TO KILL YOU, JUST TO WATCH YOU DYING.
EVERY SINGLE WORD FROM YOUR MOUTH IS PRAYER FOR YOUR GOD,
KNOWING THAT SOMEONE'S GOING TO SPILL YOUR BLOOD.
NEVER GIVE ANYTHING TO ANYONE NEW,
OR ELSE, THE SMOKE YOU DRAG WOULD BE THE FINAL BLEW.
WITH ALL OF THESE, YOU MUST DIG YOURSELF FROM THE START
SO, THESE WORDS WOULD BE MERE JOKE WITH LOTS OF FUNNY PARTS.

Now, When will the mysterious killer successfully kill this poor, religious man?

Comment immediately if you know the answer.
