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.

Taking Christian faith lightly

"The Lord is slow to anger and great in power, and will not at all acquit the wicked..." Nahum 1.3

That word is addressed to those who are take the Christian faith lightly. Especially for those who, claiming that God is love, are deliberately living in sin, as if the love of God would make Him tolerate sin or injustice.
The LORD is slow to anger and great in mercy and love, but never clears the guilty.

Where and when?

"Then you shall again discern between the righteous and the wicked, between one who serves God and one who does not serve Him." Malachi 3.18

The promise is crystal clear: you shall discern again. And who made this promise? The Lord of Hosts. Where and when should it be fulfilled? The only place where we could see this difference is right here on Earth, and it has to be now, considering that in the Kingdom of Heaven there will be no wicked people. 
Why the delay in the fulfillment of this promise? Because the surrender to the Lord has been slow.
The difference will only be seen when those who are faithful surrender body, soul and spirit in truth.

The separation

"Depart from Me, you who practice lawlessness!" Matthew 7.23

As sure as God exists, in the near future, there will be a great separation.
For the kingdom of heaven is like a fishing net that was let down at the sea, gathering all kinds of fish. And when it is full, the fishermen drag it to shore, and seated, they choose the good ones, put them into their baskets and throw away the bad.
Would the wicked coexist with the Holy Lord of Heaven and Earth?

Afflicted

"He does not preserve the life of the wicked, but gives justice to the oppressed."

Job 36:6


The Lord always hears the cry of the oppressed, and is always ready to defend them and make justice prevail on their behalf.

Intimate

"For the wicked boasts of his heart’s desire; He blesses the greedy and renounces the LORD."

Psalms 10: 13


Many people think that God does not see what goes on in their lives. Nevertheless, He not only sees everything but is also eager to be called upon.

Desires

"The nightmares of the wicked come true; what the good people desire, they get." Proverbs 10:24

When there's total trust in God, He satisfies the desires of our hearts.

Everyday

"God is a just judge, and God is angry with the wicked every day." Psalms 7:11

Humanity has been contaminated with unbelief, orgies, wickednesses, and worst of all, the indifference of God's existence and power.

TEST

"The LORD tests the righteous and the wicked, And the one who loves violence His soul hates." Psalm 11:5

God examines the heart of both, righteous and wicked. And those who do not have the holy fear and take pleasure in wrongdoing cannot enter His Kingdom.
