Why Psalm 2?
Psalm 2 describes exactly what is taking place in the world today. The rulers of the nations of the earth are becoming increasingly hostile to God, His Son and His people. The Bible predicts this trend.
P2ALM: Why are the [united] nations in an uproar And the peoples devising a vain thing?  The kings of the earth take their stand And the rulers take counsel together Against the LORD and against His Anointed, saying,  “Let us tear their fetters apart And cast away their cords from us!”
The word fetters in the above passage means shackles, chains or restraints. The motive behind the idea of moving forward into the New Age is the shedding of the Old Age as in the Judeo-Christian Worldview, or the idea of an absolute truth and a moral accountability to an Almighty God. The kings of the earth are taking counsel with one another to devise this very thing. The two earthly forces vying for domination of the world are united only in that purpose. They are the New Western Age and Islam. Ultimately, they will not succeed.
 He who sits in the heavens laughs, The Lord scoffs at them.  Then He will speak to them in His anger And terrify them in His fury, saying,  “But as for Me, I have installed My King Upon Zion, My holy mountain.”  “I will surely tell of the decree of the LORD: He said to Me, ‘You are My Son, Today I have begotten You.  ‘Ask of Me, and I will surely give the nations as Your inheritance, And the very ends of the earth as Your possession.  ‘You shall break them with a rod of iron, You shall shatter them like earthenware.'”
Christ is coming back as the Warrior of warriors to bring an end to this rebellion.
 Now therefore, O kings, show discernment; Take warning, O judges of the earth.  Worship the LORD with reverence And rejoice with trembling.  Do homage to the Son, that He not become angry, and you perish in the way, For His wrath may soon be kindled. How blessed are all who take refuge in Him!
Even still, God, out of His mercy, reasons with us to take refuge in His Son before this day comes [1 Timothy 2:3-4; 2 Peter 3:9].
