The righteous teach

"Let a righteous man strike me—that is a kindness; let him rebuke me—that is oil on my head. My head will not refuse it, for my prayer will still be against the deeds of evildoers." Psalm 141.5

A righteous person teaches and those who are also righteous learn. For them, although the learning process may be painful or feel like an act of injustice, they know it is for their own good and accept it with gratitude.
But it is not so with the wicked, that is, those who are born of the flesh. They feel it as injustice, complain, get hurt, angry, do not accept it and even want revenge. But it is only natural, after all, the darkness hates the works of the light.

FURY OF THE OPPRESSOR

"And you forget the Lord your Maker, who stretched out the heavens and laid the foundations of the earth; you have feared continually every day because of the fury of the oppressor, when he has prepared to destroy. And where is the fury of the oppressor?"

    Isaiah 51:13

God gets angry with those who have Him as Lord, yet fear other mortals and the oppressor from hell.

Where is the fury of the oppressor? Who is He?

All the enemies of our God are crushed like worms beneath our feet. They know that, but sometimes, we forget.
