'Belonging' in the Bible

Yet when we are among mature believers we do speak words of wisdom; a wisdom not belonging, however, to the present age nor to the leaders of the present age who are soon to pass away.

Do you not know that we are to sit in judgement upon angels--to say nothing of things belonging to this life?

If therefore you have things belonging to this life which need to be decided, is it men who are absolutely nothing in the Church--is it *they* whom you make your judges?
