His strength is perfect (Illustrated) 

I can do all things
Through Christ who gives me strength,
But sometimes I wonder what He can do through me;
No great success to show, No glory on my own,
Yet in my weakness He is there to let me know . . .
CHORUS
His strength is perfect when our strength is gone;
He'll carry us when we can't carry on.
Raised in His power, the weak become strong;
His strength is perfect, His strength is perfect.
We can only know
The power that He holds
When we truly see how deep our weakness goes;
His strength in us begins
Where ours comes to an end.
He hears our humble cry and proves again . . .
(chorus)
