From J. C. Ryle:
There is no more painful sign of an unhealthy state of soul than an utter absence of spiritual thirst.
But who is there among the readers of this paper that feels the burden sin and longs for peace with God?... You are the man that ought to thank God. A sense of sin, guilt and poverty of soul is the first stone laid by the Holy Ghost, when He builds a spiritual temple. He convinces of sin.
It is not when we begin to feel good, but when we feel bad, that we take the first step towards heaven.
To realize our spiritual need, and feel true spiritual thirst, is the ABC in saving Christianity.
