Bunyan and Suffering

John Bunyan comments on 2 Corinthians 1:9 'We had the sentence of death in ourselves, that we should not trust in ourselves but in God who raises the dead':

‘By this scripture I was made to see that if ever I would suffer rightly, I must first pass a sentence of death upon every thing that can be properly called a thing of this life, even to reckon myself, my wife, my children, my health, my enjoyment, and all, as dead to me, and myself as dead to them. The second was, to live upon God that is invisible, as Paul said in another place; the way not to faint, is to "look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal.’
