Acts 15:10: Who can the yoke of Moses bear

Who can the yoke of Moses bear?
It drives a sinner to despair;
Crushes the soul, but not relieves,
Commands, but no assistance gives,
Confounds, but not destroys our pride,
And lets us still in death abide.

The law our irksome duty shows,
But no obedient power bestows,
It brings us light and knowledge vain
More to increase our sin and pain,
It aggravates our heaviest load,
And leaves us to the curse of God.

But Jesus' death hath set us free
From sin and curse and penalty;
For us He purchased on the cross
A power to keep His righteous laws,
To bear His easy yoke, and prove
All His commands fulfil I'd in love.
