“Revenge is MINE”

means YOU NEVER take revenge. You do the right thing, but
you do not take revenge because the results of the actions of (s)he, whom you perceive as your perpetrator, are NOT up to YOU, but up to a HIGHER POWER.

'The true test of a man's spirituality is his ability or inability to remain content when nothing exciting is happening.'  Vernon Linwood Howard
