"Lord, it is on my sea that you walk; it is on the billows of my soul that You draw near. The first proof of Your presence is inward storm. It is by the rolling of the waves of conscience that I know You to be nigh. 
When You were absent from my heart there was no  wind, there were no waves; the sea was a great calm. But when Your feet touched the waters my storm arose - the storm of my conscience. The thing which yesterday looked harmless became fraught with peril. The deeds on which yesterday I gazed with complacency, spread blackness in my soul. The valleys became mountains, the trifles loomed as deadly crimes, and I beat upon my breast and cried, "Lord, be merciful unto me! That was my hour of communion with You O God." George Matheson.
