The 1 Corinthians passage says that everyone is given the same Spirit, but different ways to use it in ministry. Everyone in this musical group is playing the guitar, but each is playing a different part of the music. When they play together, following the notes and timing, they sound beautiful. But if one of them were to go off on their own riff while the others were playing their parts, it would become immediately discordant. It takes teamwork to produce a pleasing sound unto the Lord. There may be a time for each to go solo, but together they provide a fuller, richer sound.
