How do we know that Jesus fulfills the prophecies about liberation?

In Luke 4:18-21, Jesus reads from Isaiah 61 and explicitly states, 'This day is this scripture fulfilled in your ears.' This proclamation establishes Him as the fulfillment of Old Testament prophecy regarding liberation. He explains His purpose as the anointed one sent to heal the brokenhearted and liberate the captives, directly linking His ministry with the prophecies of Isaiah. This direct citation and application of prophecy demonstrate His divine authority and the sovereign purpose of God in salvation.
