Ashamed of Christ! my soul, disdain
The mean, ungenerous thought:
Shall I disown that Friend, whose blood
To man salvation brought?
With happy news of love and peace
From Heav’n to earth He came:
For us endured the painful cross,
For us despised the shame.
At His command, we must take up
Our cross without delay:
Our lives—and thousands more like ours
His love can ne’er repay.
Each faithful sufferer Jesus views
With infinite delight;
Their lives to Him are dear; their deaths
Are precious in His sight.
To bear His name, His cross endure,
Our highest honor this!
Who nobly suffers now for Him,
Shall reign with Him in bliss.
But should we in the evil day
From our profession fly,
Jesus, our Judge, before the world,
The traitor will deny.
