JMNT(i)
11 being progressively enriched unto abundance within every person (or: in everything) [leading] into complete singleness [of purpose] and simplicity [of being] for all generosity (liberality), which constantly produces (works down; accomplishes) thanksgiving to God through our midst [or, with B: which repeatedly works in accord with God's ease of grace, instilling gratitude through the midst of us],
12 because the attentive serving and dispensing of this public duty and service is not only repeatedly replenishing (aiming toward filling back up again) the needs (results of defaults; the effects of shortcomings, lacks or deficiencies) pertaining to the set-apart folks (the holy ones; the saints; or: the sacred [communities]), but further is also progressively superabounding (bringing excessive amounts) through many expressions of gratitude to God (or: by means of many examples of the goodness of grace in God)
13 through the evidence which is shown by this attending service and dispensing: folks constantly glorifying God and praising His reputation because of (or: based upon) the subjoined, humble alignment, the supportive arrangement and the subjection in appended shelter – which is your accordance to the message and agreement in thought (and thus: your profession of saying the same thing), [showing] assent unto Christ's message of goodness, ease and well-being, as well as by [the] simplicity and generosity of the partnership of common-existence sharing unto them, and unto the midst of all people,
14 even by their request over [the situation of] (or: on behalf of) you folks – from people constantly longing and yearning for you. [It is] because of God's transcendent favor and surpassing grace [resting] upon you people –
15 grace and joyous favor, in and by God, [superimposed] upon His free gift – which is a wonder beyond description (or: added to His indescribable gratuity)!
