Have you ever discussed the background of the main song 213?

By the grace of God.

1. The background of song 213 of "Have You Ever Sung the Lord?" is that we are cleansed through the precious blood of the Lamb, which is all due to God's grace.

2. The words and music of "Have I Ever Been the Main Song" were written by the prolific evangelical writer Hoffman, and it is one of the 213 poems.
