There Must Be Something More - by James Horner on the Deliverance radio program.

In this program, first broadcast in 1991, James Horner exhorts us to reach out for more in our lives of Faith and find a bigger God than we ever thought possible. Realms of the Holy Spirit we hardly imagined possible but see in the lives of those in the early church in Bible days. Of course Jesus' ministry is our benchmark: as He said "you will do greater things than I did".
The music for the program is brought by Keith Green, local singers Nell Hire and Robin Rea and on the harp, Carol McClure. The message begins at 08m 38s.
