"The text proceeds to say that Jesus was sent to free the imprisoned, to grant sight to the blind, to free the oppressed and to herald the grace of God. Such a gracious ministry is due to the work of the Spirit in Jesus' life. It flows from the Spirit's anointing. We should also observe that Jesus described the whole of His ministry here, so that every dimension of His work depended on the anointing power of the Spirit. Every good work detailed in Luke stems from the Spirit Himself. Jesus truly was the bearer of the Spirit, the Man marked out by the Spirit, the Man was uniquely strengthened by the Spirit".
