It can turn you and me into ‘threshing machines’ (Is 41.15); thresh away doubt in the amazing love of God. I’ve seen hate and I’ve seen indifference, but

nothing shakes my core like the Presence of Him who can touch my heart of stone.

..nothing moves me like the Fountain of His tender mercy new every morning. Oh nothing shakes me to the core like His still small voice insisting, pursuing my weakening breath, pleaing that I look away from stubborn doubt into His permanence.
