Curiosamente aos 26 anos M'Cheyne visitou a Terra Santa e ao voltar da mesma consequentemente montou um ministério para alcançar os Judeus em sua paróquia.
Em sequência irei reproduzir o poema. A estrofe que Spurgeon citou é a terceira.
I Am DebtorWhen this passing world is done,When has sunk yon glaring sun,When we stand with Christ in glory,Looking o'er life's finished story,Then, Lord, shall I fully know- Not till then - how much I owe.When I hear the wicked callOn the rocks and hills to fall,When I see them start and shrinkOn the fiery deluge brink,- Then, Lord, shall I fully know -Not till then - how much I owe.When I stand before the throne,Dressed in beauty not my own,When I see thee as thou art,Love thee with unsinning heart,Then, Lord, shall I fully know- Not till then - how much I owe.When the praise of heav'n I hear,Loud as thunder to the ear,Loud as many water's noise,Sweet as harp's melodious voice,Then, Lord, shall I fully know- Not till then - how much I owe.Even on earth, as through a glassDarkly, let Thy glory pass,Make forgiveness feel so sweet,Make Thy Spirit's help so meet,Even on earth, Lord, make me knowSomething of how much I owe.Chosen not for good in me,Wakened up from wrath to flee,Hidden in the Saviour's side,By the Spirit sanctified,Teach me, Lord, on earth to show,By my love, how much I owe.Oft I walk beneath the cloud,Dark, as midnight's gloomy shroud;But, when fear is at the height,Jesus comes, and all is light;Blessed Jesus! bid me showDoubting saints how much I owe.When in flowery paths I tread,Oft by sin I'm captive led;Oft I fall - but still arise- The Spirit comes - the tempter flies;Blessed Spirit! bid me showWeary sinners all I owe.Oft the nights of sorrow reign- Weeping, sickness, sighing, pain;But a night Thine anger burns- Morning comes and joy returns;God of comforts! bid me showTo Thy poor, how much I owe.
