When I was reading this Psalm, it made me think of the conditions today, and the governments today. They do not want to follow the Lord's ways. They think their ways are superior. They actually are deluded into thinking they will prevail against the Most High God, much as Lucifer thinks he will.
WHY do the heathen rage, and the people imagine a vain thing? 2 The kings of the earth set themselves, and the rulers take counsel together, against the LORD, and against his anointed, saying, 3 Let us break their bands asunder, and cast away their cords from us. 4 He that sitteth in the heavens shall laugh: the LORD shall have them in derision. 5 Then shall he speak unto them in his wrath, and vex them in his sore displeasure.
The nations are plotting right now. They are scheming about setting up their global government, and they are almost giddy as they look at how close they are to fulfilling their vision, yet the Most High God that they despise so much is laughing at them, because He knows that their end is near.
The rulers of the world are planning to set up their global government, and they have their own King they are looking to put in place to govern the whole world. Unlike our King, theirs is evil. He stands for everything that is bad and vile. The rulers of the earth will give their power over to this wicked individual, but hear the Word of the Lord.
6 Yet have I set my king upon my holy hill Zion. 7 I will declare the decree: the LORD hath said unto me, Thou art my Son; this day have I begotten thee. 8 Ask of me, and I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession. 9 Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter's vessel. 10 Be wise now therefore, O ye kings: be instructed, ye judges of the earth. 11 Serve the LORD with fear, and rejoice with trembling. 12 Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him.
The one that will rule the world with a rod of iron is the Lord Jesus Christ. The first time He came to earth, He came as a Lamb, and was slain by His own creation. When He returns, He will come as a conquering King.
And she brought forth a man child, who was to rule all nations with a rod of iron, and her child was caught up unto God, and to his throne. Revelation 12:5
And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God. And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS. Revelation 19:15-16
