The prophets speak of God's visitation in both salvation and judgment, and Luke 1:68 celebrates the Lord God's visitation and redemption of his people.
At Nain the crowd said God had visited his people; now Jesus declares Jerusalem culpable for failing to recognize its visitation.
The term alone does not prove Jesus is God, but Luke's cumulative visitation pattern strongly associates God's promised coming with Jesus' ministry.
The disciples praise God, while Jerusalem as a city fails to recognize the visitation.
The contrast separates those who perceive God's work in Jesus from the city that rejects it.
