Question:
How do we “sing with the Spirit” (1 Corinthians 14:15). What does it sound like?

Answer:
Singing with the Spirit is done by “making melody in your heart to the Lord” (Ephesians 5:19). Singing or praying with the Spirit would be to sing or pray what is understood by all (1 Corinthians 14:16), and it would also edify all who heard (verse 12).
