Remember : we are growing toward Christian maturity - being conformed to the image of Christ - and this is one of the things we are blessed to pursue.
being blameless, above reproach (as in Titus 1:6,7, 1 Tim 3:2)
a. unaccused - without a deserved accusation against us (especially in a court of law)
b. unaccusable - having nothing an adversary can seize upon with which to base a charge against us
inculpable, blameless, unrebukable, irreprehensible - not deserving rebuke or censure (a closer translation giving the true meaning of the word)
so not merely unaccused (free from any deserved legal charge)
but also unaccusable (free from anything an adversary might use against us)
