So I have written new last lines for each stanza. If anyone cares to use these altered lyrics, I've made them Creative Commons. The altered lines are italicized.
Go to dark Gethesmane
All who feel the tempter's power
Your Redeemer's conflict see
Watch with him one bitter hour
Turn not from his griefs away
Humbly watch your Savior pray
Follow to the judgment hall
View the Lord of life arraigned
Oh the wormwood and the gall!
Oh the pangs his soul sustained!
Shun not suffering, shame, or loss
Follow while he bears the cross
Calvary's mournful mountain climb
There, adoring at his feet,
Mark that miracle of time
God's own sacrifice complete.
"It is finished!" hear him cry;
Jesus Christ was sent to die.
Early hasten to the tomb
Where the laid his breathless clay
All is solitude and gloom
Who has taken him away?
Christ is risen! He meets our eyes!
Savior, bring us so to rise.
Original lyrics James Montgomery, 1771-1854
Likely enough someone can do better than that on the alterations. But in the meantime, if someone wants to sing more Christ-centered lyrics for a Lenten meditation, this will be an inch in the right direction.
