The Expositor's Bible: The Epistle to the Philippians. Robert Rainy

There may be instances in which, with our best wisdom, we find it hard to disentangle clear principles, or state plain grounds which rule the case; yet love, growing and exercised, has its percipiency: it has that accomplished tact, that quick experienced taste, that fine sensibility to what befriends and what opposes truth and right, which will lead to right distinctions in practice. So you discriminate by the sense of taste things that differ, though you can give no reason to another, but can only say, "I perceive it." In this sense "he that is spiritual judgeth all things."

      For all this the aid of the Holy Spirit is held out to us, as we may see in 1 John ii. He makes love to grow, and under that master influence unfolds the needed wisdom also. So comes the wisdom "from above, which is first pure, then peaceable, gentle, and easy to be entreated, full of mercy and of good fruits, without partiality and without hypocrisy" (James iii. 17). It is hidden from many wise and prudent, but God has often revealed it unto babes.
