...,and I guess it being a solo album made Neal want to bust out talking about God and Jesus by name again.
Well, I think the subject matter kind of demands it.
To give some context to the lyrics, for those who may not know the specifics of the story, most of the album (and that song, specifically) is told from the perspective of Paul, the Apostle. Most of the story takes place before he was an Apostle. Paul was originally named Saul. He was a Jew who was a disciple of one of the greatest Jewish rabbis of the day, and as a young man, was basically a protege who was being groomed to be THE next big thing in Judaism. As recorded in the first several chapters of Acts of the Apostles, after Jesus's death, burial, and resurrection, they Apostles were repeatedly arrested, beaten, and threatened for trying to teach that Jesus rose from the dead, and that people should follow him. In chapter 7, we see that Stephen, a disciple, was publicly killed. Acts 8:1 says that "Saul approved of his execution." The following verses are relevant to the new single. It talks about Saul leading a great persecution against the Christians in Jerusalem and the surrounding area, and about he got letters of approval from the leaders to drag suspected Christians from their homes and into prison, some (or all) of whom were then executed. He was trying to destroy Christianity and everything associated with it, and believed he was doing so at God's direction. This is what the lyrics of In the Name of the Lord are about.
