Christ, Our Conquering King!

Question 45 of the Westminster Larger Catechism asks, How does Christ execute the office of a king? And answers it this way: "Christ executes the office of a king, in calling out of the world a people to himself, and giving them officers, laws, and censures, by which he visibly governs them; in bestowing saving grace upon his elect, rewarding their obedience, and correcting them for their sins, preserving and supporting them under all their temptations and sufferings, restraining and overcoming all their enemies, and powerfully ordering all things for his own glory, and their good; and also in taking vengeance on the rest, who know not God, and obey not the gospel."

There's a lot there, and I won't even try to address it all.

In Psalm 110:1, the Father gave a promise to the Son as part of the intra-Trinitarian covenant in prehistory: "Sit at My right hand, until I make Your enemies Your footstool" (applied to the Son in Hebrews 1:13). The Father had determined to glorify the Son by giving Him visible rule over the creation. History has been the record of the fulfillment of that promise, as the rule of Christ is established over the kingdoms of the world (compare Daniel 2:44-45, Revelation 11:15).

The theme of the royal destiny of the Son is especially described in the second Psalm:

"'As for Me, I have set my King
     on Zion, My holy hill.' 
I will tell of the decree:
     The Lord said to Me, 'You are My Son;
today I have begotten You.       

     Ask of Me, and I will make the nations Your heritage,
and the ends of the earth Your possession.
     You shall break them with a rod of iron
and dash them in pieces like a potter’s vessel.' 
     Now therefore, O kings, be wise;
be warned, O rulers of the earth.
     Serve the Lord with fear,
and rejoice with trembling.
     Kiss the Son,
lest He be angry, and you perish in the way,
     for His wrath is quickly kindled. 

Blessed are all who take refuge in Him."

- Psalm 2:6-12 

What we don't see here is a description of the means of that conquest. There are militaristic expressions, but no mention of armies or weapons. In fact, Scripture denies a spiritual role for weapons of war: "The weapons of our warfare are not of the flesh but have divine power to destroy strongholds" (II Corinthians 10:4). So, no tanks or nuclear bombs, or even swords or arrows. What then?

Some of Jesus's last words during His earthly ministry are found in the Great Commission: "Jesus came and said to them, 'All authority in heaven and on earth has been given to Me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age'" (Matthew 28:18-20). Here, Jesus claims "all authority," that is, the very delegation of royal prerogative we find in Psalm 2. As King, what assignment does He then give His captains, the Apostles (and we after them)? To disciple the nations, part of which is to teach them to obey His Law.

Therefore, the answer to the assignment in Psalm 2 is no military conquest. Nor is it some waving of a divine hand from heaven. This is in spite of the obvious fact that either one would be within the power on omnipotent deity. Rather, the submission of all things to the crown rights of Jesus is through His people, as we proclaim the Gospel and train the nations to live as Christians. Evangelism and missions will conquer the world, because our Savior is already king!
