The Spirit of the Lord is upon Me, because He hath anointed Me to preach the gospel to the poor; He hath sent Me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, to preach the acceptable year of the Lord (Luke 4:18-19).
And what means the sending away the broken in freedom? It is the letting those go free whom Satan had broken by the rod of spiritual violence.
And what means the preaching the acceptable year of the Lord? It signifies the joyful tidings of His own advent, that the time of the Lord, even the Son, had arrived.
For that was the acceptable year in which Christ was crucified in our behalf, because we then were made acceptable unto God the Father, as the fruit borne by Him.
Wherefore He said, “When I am lifted up from the earth, I shall draw all men unto Myself.” And verily He returned to life the third day, having trampled upon the power of death: after which He said to His disciples, “All power has been given Me….”
That too is in every respect an acceptable year in which, being received into His family, we were admitted unto Him, having washed away sin by holy baptism, and been made partakers of His divine nature by the communion of the Holy Spirit.
That too is an acceptable year, in which He manifested His glory by ineffable miracles: for with joy have we accepted the season of His salvation, which also the very wise Paul referred to, saying, “Behold, now is the acceptable time, behold now is the day of salvation.”
This is the day when the poor, who formerly were sick by the absence of every blessing, having no hope and being without God in the world, such as were the gentiles, were made rich by faith in Him, gaining the divine and heavenly treasure of the Gospel message of salvation.
By this they have been made partakers of the kingdom of heaven, co-partners with the saints, and heirs of blessings such as neither the mind can conceive nor language tell.
“For eye, it saith, hath not seen, and car hath not heard, neither have entered into the heart of man, the things that God hath prepared for them that love Him.”
[...] But by the bruised in heart, He means, those who have a weak and yielding mind, unable to resist the attacks of their passions, and so carried along by them, as to seem to be captives: to these He promises both healing and forgiveness.
