Was Barnabas described as a preacher unto the gentiles or one whose light goeth not out or a good man full of the Holy Spirit and faith or a bringer of glad tidings?

Barnabas is primarily described as a good man, full of the Holy Spirit and faith in the New Testament. He played a significant role in the early Christian church, particularly in preaching to the Gentiles and encouraging believers. While he is associated with bringing glad tidings, the specific characterization of being a "preacher unto the Gentiles" is more closely linked to other apostles, like Paul.
