JMNT(i)
 19 And so, we continue having (or: constantly hold) 
the Idea which was spoken ahead of time in and as Light (or: the prior-enlightened Thought and Reason; or: the Prophetic Word) 
more confirmed (validated; established; certain), 
by which (or: in which) 
you folks continue doing beautifully (performing ideally; producing finely), 
while continuously holding toward (= playing close attention to) [
it] 
as to a lamp continually shining within a parched place – until which [
time or occasion] 
the Day may shine through and a light bearer [= a morning star] 
may rise within your hearts (or: constantly heeding, as to a lamp progressively making things appear in a dark, dingy or dirty place, until that the Day can dawn, and a light-bringer can arise in union with your core and innermost being),
 
20 constantly knowing this first, that every (or: all) 
previously enlightened information of Scripture [
p72: prophecy and Scripture] 
is not coming to be unbound upon its own (or: is not being born of its own unloosing; or: is not becoming its own explaining; or: is not coming into existence upon one's own releasing),
 
21 for you see, previously enlightened information (or: prophecy) 
was (or: is) 
not at any time brought by (or: in; for) [
the] 
will (intent; resolve; purpose) 
of a human, but rather being continuously carried by (or: swept along under [the influence of]) [
the] 
set-apart Breath-effect (or: Holy Spirit), [some MSS add: set-apart; holy] 
people spoke (or: speak) 
from God.
