Samuel Rutherford this Morning

In my continual reading of The Letters of Samuel Rutherford this morning, I came across this wonderfully encouraging passage on temptation. Rutherford writes:

I find it most true, that the greatest temptation out of hell is to live without temptations. If my waters would stand, they would rot. Faith is the better for the free air and the sharp winter-storm in its face. Grace withereth without adversity. The devil is but God's master-fencer, to teach us to handle our weapons.
