What is the gospel song that has the lyrics Now I raise mine Ebenezer?

"Come Thou Fount of Every Blessing" has the line "Here I raise my Ebenezer."

It's a hymn, not a gospel song. You can see the lyrics at the link below.

"Eben-ezer" means "stone of help." Samuel raised a large stone as a memorial to the help he had received from God. There is more information linked below.
