One of the things I like about Young Pilgrim's Progress is that it shows that the Christian life is a journey that is not easy, and can only be completed with God's help.
In Chris Wright's version of Bunyan's tale, only a few people are on the journey, and even some of these turn back, because they find it too hard.
I like the way he shows us that it is only the people who complete the journey (with God's help) who end up in the celestial kingdom.
This is quite different from the way the gospel was presented to us as children. We were assured that if we met Jesus at the cross and asked his forgiveness for our sins, the journey was over!
In Bunyan's book, the cross is only the beginning. When Pilgrim sees the cross, and understands Jesus took his place, he loses his burden and knows his sins are forgiven. He is confident that God will keep him safe and lead him to his destination, but he also knows that he has a long way to go and must keep on the path to receive God's promise of life forever with him.
