"Jesus has Authority" - he's the boss, the one in charge, and you can see it through the miracles he did.
Where John focusses on "signs" (see Songs about Miracles #1), Mark in his Gospel shows us Jesus' Authority - and he's got real authority in bucket loads: over nature, sickness, sin, and even life and death.
The Sunday School Song "Jesus has Authority" looks at some of these miracles from Mark's and John's Gospels, and encourages us to see Jesus' authority, and so respond with faith in him as the "way, truth and life" (John 14:6).
There are verses about the wedding at Cana, the healing of the paralytic, Jairus' daughter, and the calming of the storm. It's a song that has a free rhythm, and works really well with solo guitar or piano, or just unaccompanied.
