The Ministry of Jesus was one of deliverance freeing people from the bondage of Satan so that they were able to do the work of The Kingdom
Isa 61:1 The Spirit of the Lord GOD is upon me; because the LORD hath anointed me to preach good tidings unto the meek; 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;
Isa 61:2 To proclaim the acceptable year of the LORD, and the day of vengeance of our God; to comfort all that mourn;
Isa 61:3 To appoint unto them that mourn in Zion, to give unto them beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness; that they might be called trees of righteousness, the planting of the LORD, that he might be glorified.
Isa 61:4 And they shall build the old wastes, they shall raise up the former desolations, and they shall repair the waste cities, the desolations of many generations.
So it is basic to the Christian life if people want to serve Jesus in the way He desires them to without the effects of Satan in them hindering the work of Jesus.
