Trinity

The three and one and one in three
  today we try to unravel the Trinity
We say we can explain the mystery
  here within since time began
The force which brings light, or the
  flames which burn, moving fast
Ripping through bringing a new
  something which is old and can't
Be contained within simple words
  explanations run short of the unknown
Drowning,
    quenching,
        burning,
            running
  filling,
    emptying,
        desire,
            faith,
    free
