Helaman 6:3

Nevertheless, the people of the church did have great joy, because of the conversion of the Lamanites; yea, because of the church of God, which had been established among them. And they did fellowship one with another, and did rejoice one with another, and did have great joy.

But the church people had great joy because the Lamanites had changed. They were happy about God’s church that had been set up among the Lamanites. They were friends with each other. They were happy with each other. They had great joy.

But the believers in the church celebrated. They were overjoyed to see the Lamanites coming to God and joining the church. They welcomed each other warmly and shared deep joy together.
