Marcelo said:All four gospels are for all of us, but Matthew was especially written for the Jews, Mark for the Romans, Luke for the Greeks and John for all the world.
The gospels were written for all the world, but only the Jews were supposed to obey the commandments of Jesus related to the law of Moses. After the death of the Lord on the cross there was a long transition period between the Old and the New Covenant, but eventually all Jews were freed from the Law.
Inward Jew as born again of the incorruptible Spirit of the word of God . Or a outward Jew pertaining to the flesh?
I think Jesus was preaching to all Jews (religious or not). If a non-religious Jew happened to be present at one of Jesus' sermons and got moved by the Holy Spirit to follow the Lord, that would be nice. The recently converted Jew would start attempting to follow the earthly Jesus and then, after the cross, with the baptism of the Holy Ghost, he would actually follow the risen Jesus.
