In will interpret this as your lack of understanding concerning the concept of "
parousia." The pedestrian use of the word simply means "an arrival" or "to arrive." But the New Testament also uses the word according to Roman tradition to speak about the official arrival of a king or other royal personages.
The word parousia in the context of Roman kings referred to the ceremonial arrival or presence of a ruler, often an emperor, in a city or region. It signified a grand event where the city prepared extensively to welcome the king or emperor, showcasing their loyalty and reverence. This term, rooted in Greek, literally means "presence" or "arrival" and was associated with the pomp and splendor of such occasions.
Jesus' entrance into Jerusalem on a donkey, celebrated as the Triumphal Entry, does share some similarities with the Roman kings' parousia, but it also stands in stark contrast. Both events involved a ceremonial arrival, public acclaim, and symbolic gestures. In Jesus' case, the crowd spread palm branches and cloaks on the ground, shouting "Hosanna," which was a cry of praise and salvation.
However, while Roman kings or emperors often arrived in grand processions with displays of power and wealth, Jesus chose a humble donkey, fulfilling the prophecy in Zechariah 9:9 about the Messiah coming "gentle and riding on a donkey." This choice emphasized humility and peace rather than dominance and grandeur. This was the First Advent.
Interestingly, Christian theology later adopted this concept to describe the anticipated Second Coming of Christ.
First Advent:
Matthew 21:9 The crowds going ahead of Him, and those who followed, were shouting, “Hosanna to the Son of David; Blessed is He who comes in the name of the Lord; Hosanna in the highest!”
Second Advent:
Matthew 23:39 For I say to you, from now on you will not see Me until you say, ‘Blessed is He who comes in the name of the Lord!’”
Unlike the Amillennial position, which does not support the idea of a future, literal earthly reign of Jesus, the Premillennial position correctly supports the earthly reign of Christ just as he predicted. He explicitly says that he will arrive on earth in a Roman-style triumphal entry when Israel will once again say, "Blessed is he who comes in the name of the Lord," showing their loyalty and reverence. That is the moment when Israel will bow the knee.
