Thine for Ever! God of Love (Tune: Brinkwells - 4vv) [with lyrics for congregations] 

"Thine for Ever! God of Love" was written by Mary Fawler Maude in 1847. She wrote, "It was written in 1847 for my class in the Girls' Sunday School of St Thomas, Newport, Isle of Wight, and published in 1848 at the beginning of a little book called "‘Twelve Letters on Confirmation,' by a Sunday School Teacher."
The tune is 'Brinkwells', written by Robert Walker, named after his house, the remote woodland cottage that was Elgar's Sussex home from 1917-1921. It appears only in the New English Hymnal.
This performance is by The Chapel Choir of Marlborough College.
