When the wicked came to Christ in penitence, they were deeply ashamed. That is as true then as it is today. That is the mark of true repentance.
But now the righteous are instead ashamed of righteousness. We are ashamed of plain declarations against sin.
We are become salt that has lost its savor, for we cannot save anybody while we are ashamed to speak plainly against sin.
How are we salt if we have become enamored with the ways of the world, instead of being enamored with the truths of God.
When the righteous are ashamed of God’s declarations against sin, then they have become ashamed of God’s righteousness. We have become ashamed of a God that cannot look upon sin with the least degree of allowance. How will we remain his people while we are ashamed of his nature, and embarrassed to declare his nature to the world?
