"He hath sent me to bind up the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound;" (Isaiah 61:1)
To a nation that was under captivity, the words of Isaiah brought comfort and also a glimpse of their future. The Word of God is relevant for all times. A student of God's word doesn't dwell in uncertainty. His conviction comes from the understanding of God's word. We are eagerly awaiting our Savior who would come and change our lowly bodies into the likeness of His glorious body. We would dwell with Him and we are blessed with this hope. When the people of Israel heard this prophecy from Isaiah, they were expectant of that Messiah who would change their captivity. The physical state of Israel is the spiritual state of many in captivity. When we are under the captivity of sin we end up broken hearted. There might be temporary pleasures but the wounds that would be caused because of sin would be fatal.
Thanks be to God - the Servant of God came down as the Lord Jesus came in search of sinners. There is no one like our Lord Jesus who can bind up the brokenhearted. Our Lord Jesus proclaims liberty to the captives. St. Paul later visualizes this in the epistle to Ephesians chapter four as He sees our Lord taking captivity captive and distributing gifts among the church. The prison doors are opened and people who are bound are released. This was literally fulfilled as the Lord Jesus came down and proclaimed the release of all who were bound by sin. You can be released from every captivity as you believe in the work of the Lord Jesus Christ.
