A Dirty Look
What is "a dirty look"? We do it so naturally that it's been superfluously driven out of normal behavior by those who immediately recognize its meaning, though maybe not consciously. A dirty look is an expression of confused surprise that is used to communicate an inquiry as to why or why not the opposite of what was just seen in a person was not done. It's a subtle accusation - as soft as one can be - and it's been raged against to the point of giving it a dirty name in order to promote its disuse. It's easy to imagine in past generations Christians thinking it a polite way to communicate that the action in question is beyond one of mere displeasure, but on the order of obscenity, and we can imagine those Christians thinking that it's a nicety to presuppose for the perpetrator that the action is also surprising, and that this is the least possible admonishment that could be made about it. Well, the World didn't like it, and, indeed, the Bible does not tell us to admonish the World, so let us pray to keep our opining to ourselves in front of it, walking circumspectly with gentleness and wisdom.
Open admonishments are better than subtle ones, because managing others' emotions is obscene when the mind needs the openly stated truth. Admonish the Church openly, Church, and let us become strong in righteousness, for the glory of God and for our own great gladness!
No gambit will work outside the free and particular confines of God's written Word, which The Holy Spirit illuminates in us, especially as we employ all we know, growing and gathering new insight from it in waves. Freely do it all well, admonishing your sibling in Christ, along with teaching, rebuke and exhorting, singing Psalms, hymns and spiritual songs in the Lord, taking every thought captive to obedience to the Lord, and praying without ceasing. Then, all of our gambits will works all over the place, because we will have put ourselves in His hands to accomplish the thing overall, and we can enjoy being a part of what He does with our little particular ways, freely - even a dirty look.
