Perfect  

Hi, koji_akagi.
Do you know I have given presentations on the ways of looking at matters other than the world suggests you.So, the discussion is going to be interesting.

Now, let me suggest another way of describing that perfect is one of the few words that have gained perfection.
None of us is perfect, so our analysis of any word can not be perfect, i.e. we can not say a word as arising imperfection, straight away. Also, since the word perfect can not be correctly associated with this imperfect world, the word perfect does not contain the imperfections introduced by this imperfect world.
Well, who is perfect? If you believe in God, you will say He is. So, perfect is concerned with the one who controls our ability to limit just below perfection. So, who are we to question the word that is meant only for one but not for us all.

I looked up perfection and came with the the word meaning as: complete, right, peaceful, sound, wholesome, and fullness. As as child you may be perfect but if you are grown and still acting like a child then you are not perfect. When you are new in believing in Christ you have much to improve. If you stay where you came in you are not striving toward perfection, which is a lifetime process. If Christ blood cleanses me than am I not perfect through Him.

In reality, 'perfect' is in relation to what you are comparing it to!
Everyone has a different perspective and expectations of 'perfect'!
And it is true, in mathematics, there is 0% variance in the answers!
Thats why I like accounting, taxes, and bookkeeping!

Actually, numbers are not perfect, since they are abstractions and not real. What is perfect possesses perfect qualities. Existence is a more perfect quality than in existence. Thus numbers would only be perfect were they not abstractions.
