looking for a song by the primative quartet

[kjv2008]

the only part of the song i know is the first verse that says, in the garden of gethsimanie on the cold and lonley ground, there knelt a man in agony as the tears kept falling down, then i heard him cry oh father above let this cup be past from me, what love for me i cannot see i dont understand.................if anyone can help it will be greatly appreciated, thanks and God Bless!!!
