Pertaining to preaching the Gospel as it relates to Salvation Good News, it was not to be for all without exception, and that has never been the case, in fact God designed the Gospel to be offensive to some people, but it was designed in the Eternal Purpose of God to be the Gospel and Good News to the poor. Jesus as He quoted the prophet Isaiah in Luke is very specific to whom He came to preach the Gospel to as it relates to Salvation Lk 4:18-22
18 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,
19 To preach the acceptable year of the Lord.
20 And he closed the book, and he gave it again to the minister, and sat down. And the eyes of all them that were in the synagogue were fastened on him.
21 And he began to say unto them, This day is this scripture fulfilled in your ears.
22 And all bare him witness, and wondered at the gracious words which proceeded out of his mouth. And they said, Is not this Joseph's son?
Jesus quotes Isa 61:1-3
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;
2 To proclaim the acceptable year of the Lord, and the day of vengeance of our God; to comfort all that mourn;
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.
Here the Preaching the Gospel is to the meek ! Ps 149:4
For the LORD taketh pleasure in his people: he will beautify the meek with salvation.
Now lets see if we can answer this question honestly, as to who it is that Jesus was anointed to preach the Good News of the Gospel to ?
