Our reference to Jesus as “Lord” is not accidental. We may not always do so consciously, sadly, but whenever we call Jesus our Lord, we are making an incredibly theological statement. We are affirming that Jesus is the one appointed by the Father to be the ruler of all creation. We ascribe such authority to none other.
This is clearly taught in Scriptures like Psalm 2. In this psalm, we envision all the nations rising up against the LORD. The kings of the earth have had it with him, and they decide that they will no longer submit to him and his “anointed”. They will be set free from his “tyranny”. Such a rebellion is hardly intimidating to the Almighty, however. This “takeover” makes him laugh in ridicule. He turns to his “anointed”, who is later revealed as the king whom God has set on Zion, and promises to hand the nations over to this king so that he may break them in pieces like a potter would smash a crooked vase.
The interesting thing about this psalm is not simply that God promises to crush rebellious regimes through his appointed/anointed king. The interesting thing is that he refers to this king as “my Son” (v.7). “Begotten” here is not a reference to his becoming a Son, but rather to his becoming the heir of all the nations as a birthright. This was repeated by Paul and by the author of Hebrews as a reference to Jesus (Acts 13:33, Heb. 1:5, 5:5). Jesus himself referred to himself as one who had all authority in heaven and on earth (Matt. 28:18-20).
We should respond, then, by heeding the words of the psalmist:
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 (vv.10-13).
And we should respond by heeding the words of our Lord:
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 (Matt. 28:29-20).
