I was having a conversation with someone at church today, after our gathered worship time, talking about the Christian life. I (highly) recommended that he read The Pilgrim's Progress (John Bunyan), for encouragement in his walk with Jesus.
It reminded me of this quote, directed at preachers, but true for any Christian walking in the way of Jesus:
“The Pilgrim’s Progress with its strong sense and homely simplicity, its poetic charm and devotional sweetness, is so rich in the choicest illustration that every preacher ought to make himself thoroughly familiar with it, and to refresh his knowledge again and again through life.”
