Straw Man rl - as already pointed out to you, authoritatively, severally, at length and in great detail, by the standard, accepted dictionary definition of "Perfect" the concept is an absolute, subject neither to qualification nor quantification, subject to no condition or modifier whatsoever, immutable; a thing, state, or condition of being may be either perfect or other than perfect, if other than perfect, if modified in any respect in relation to perfect, it by definition is not perfect - a conditional absolute is a self-cancelling absurdity.
I do not, as you erroneously allege, "reveal" I have my "own defintion in mind", I merely and explicitly ascribe to the English word "Perfect" the attributes requisite by its accepted, standard dictionary definition - no "special definition", rl, just
THE DEFINITION. You, bringing yet more straw to the discussion, attempt, via unwarranted implication, to insert the qualifier of "Passivity" into that definition.
Quite plainly and simply, once again, a thing, condition, or state of being may be and may be only perfect, in and of itself, succeptable to no change, increase, decrease, alteration, enhancement, degradation, or other modification, or it may be other than perfect and may be therefor subject to change, increase, decrease, alteration, enhancement, degradation, or other modification. A thing, condition, or state of being may be perfect, or other than perfect. It may not be more perfect, nor less perfect, it cannot be passively perfect or aggressively perfect, it cannot be greenly perfect or darkly or loudly or wetly perfect, it may, in and of itself, be only perfect in any, all, and every respect, or it may be other than perfect. There are no other options, no other interpretations.
As for
Mark 10:27, what is there to examine, let alone "answer"? According to whatever translation of Mark, the putative Jesus is purported to have told those to whom allegedly he was speaking at the time that all things are possible with God. Now, whether the particular matter at discussion was salvation, insect control, or donut making, the purported statement stands alone, and its meaning, by its words, in context, as reported by Mark, given the accepted, standard dictionary definitions of those words, is unambiguous; according to what the author of Mark wrote, that meaning unarguably is that:
WITH
TO
FOR
or
IN
GOD
ALL
THINGS
ARE
POSSIBLE
and the author of Mark goes further to clarify, making explict, amplifying, that with, to, for, or in God,
NOTHING
IS
IMPOSSIBLE
Now, either what the author of Mark wrote means what it says, or it means something else. Which is it? What do you say scripture says?
