When the Lord entered into Jerusalem on Palm Sunday, it was the only time when there was public acclamation of Him as Messiah and King. In our joining the celebration, we declare Jesus to be our Lord, which has great implications for our daily life.
The significance of this ascription of lordship to the risen Christ is also fairly clear, though it can be exaggerated. At the very least, kyrios denoted an asserted or acknowledged dominance and right of disposal of superior over inferior – whether simply master over slave, king over subject, or, by extension, god over worshiper. To confess someone as one’s “lord” expressed an attitude of subserviencey and a sense of belonging or devotion to the one so named. And if the confession was used in baptism (as seems likely in Rom. 10.9), it would also indicated a transfer of allegiance and change in acknowledged ownership. At the very least, then, the confession of Jesus as Lord betokened a life now committed to his service. (James D. G. Dunn, The Theology of Paul, p. 247)
“The followers of Jesus of Nazareth founded an early Jewish movement centered on a charismatic figure who offered hope for an ideal future in which the power of the God of Israel would be dramatically manifested and universally recognized. The movement they began was not however, the only one of its kind. Other such movements, dating back from the first century BCE to the second century CE, promised a sudden end of the present age, which they regarded as evil and corrupt, and the inauguration of a new age in which God’s people would see the wicked punished and the world ruled in righteousness.
Notably, this king accomplishes his goals not by military might; his weapon is ‘the word of his mouth,’ based on Isaiah 11.4.
One major function of the Messiah is to bring about God’s justice by defeating all agents of oppression, human and superhuman (Pss. Sol. 17.34, Ezra 13.38). However, the focus of the texts is less on the messianic figure than on the messianic age, the time when God’s justice rather than Satan or Empire, would prevail.” (The Jewish Annotated New Testament, 530, 531)
We are in Holy Week – the week in which God reveals His true nature to us. God is Holy and it turns out that holiness also means humble and self-sacrificing.
