If used with sharing time you could use cards with each letter to spell reverence and have the children hold each card as they give the poem.

R:   Reverence is true respect
      For Jesus whom we love.
      And for this chapel where we meet
      To worship him above.

E:   Each child should come in quietly
      No push, nor jump, nor run,
      But be polite and orderly
      Until the meetings done.

V:   Very softly we should speak
      And yet distinct and clear
      The soft sweet tones of children
      Our Savior likes to hear.

E:   Every child should fold his arms
      And while the prayer is said
      Should close his eyes and listen
      And always bow his head.

R:   Remember, little children,
      Be courteous and true,
      Be kind to one another
      For, this is reverence too

E:   Enter here with happy thoughts
      But don't be rough and loud
      For Jesus loves a smiling face
      But not a noisy crowd.

N:   Neat and tidy we should be
      With faces shining bright
      And if our thoughts are clean and pure
      We'll always do what's right.

C:   Cleanliness is reverence
       Let's try in all we do
       To keep the chapel neat and clean
       Now and the whole week through.

E:    Everyone should reverent be
       In every act and word
       When we are in the Savior's house,
       The chapel of the Lord.
