Acts 26:23 and Colossians 1:18 contradicts what you posted. I am confused with your last statement: "If a person was poor they were not blessed." The poor certain may be blessed. A persons financial status are not a qualifier.
The poor and sick being “cursed“ was the Jewish mindset when Jesus walked the earth in Israel during the first century.
Jesus was dealing with that mindset with His teaching about the rich man and Lazarus.
