My grace is sufficient for thee: for My strength is made perfect in weakness.@2 Corinthians 12:7

Let me but hear my Savior say,
Strength shall be equal to thy day;
Then I rejoice in deep distress,
Leaning on all-sufficient grace.

I glory in infirmity,
That Christ’s own power may rest on me;
When I am weak, then am I strong,
Grace is my shield, and Christ my song.

I can do all things, or can bear
All sufferings, if my Lord be there;
Sweet pleasures mingle with the pains
While His left hand my head sustains.

But if the Lord be once withdrawn,
And we attempt the work alone;
When new temptations spring and rise,
We find how great our weakness is.

So Samson, when his hair was lost,
Met the Philistines to his cost;
Shook his vain limbs with sad surprise,
Made feeble fight, and lost his eyes.
