Were they ashamed when they had committed abomination? No! They were not at all ashamed; Nor did they know how to blush. Therefore they shall fall among those who fall; At the time I punish them, they shall be cast down,” says the Lord. (Jeremiah 6:15, NKJV)
Shame over one’s sin ought to motive repentance and a return to the Lord. But, the people of Judah had so entrenched themselves in sin that they were not at all ashamed. They had lost their ability to blush over things that are disgraceful and repugnant to God. Not unlike many in our time, they abandoned following the truth of God and reveled in their sins of idolatry and immorality. God assured them their sin brought them under His punishment. Does the sight of sin cause you to blush? Or, have you adapted to its presence, even starting to participate in sin without embarrassment? Christians must have such an aversion to sin that we turn away from its shame. The shame and guilt associated with sin should deter us from becoming comfortable with it.
