There're several recordings of this gospel, but I have found only one verse.
DIG A LITTLE DEEPER
(by Kenneth Morris)
I want to dig a little deeper in God's love,
Dig a little deeper in God's love,
Dig a little deeper in the storehouse of God's love.
Gonna walk on like a Christian should,
Talk on like my Jesus would,
Dig a little deeper in the storehouse of his love.
(From: Anthony Heilbut, The Gospel Sound, Limelight, 1971, 1985, p. 11)
