Follow your heart - John Bunyan

His basic message is meant to put steel in their backbone and to encourage them to run the race and seek the prize of Heaven. He comes to remind them that they have an enemy who seeks to destroy them.

Now, this... Mountain signified the Church of the living God; the Sun that shone thereon, the comfortable shining of his merciful Face on them that were therein; the Wall, I thought, was the Word, that did make separation between the Christians and the World; and the Gap which was in this Wall, I thought was Jesus Christ, who is the way to God the Father. But forasmuch as the Passage was wonderful narrow... it showed me that none could enter into Life, but those that were in downright earnest, and unless also they left this wicked World behind them; for here was only room for Body and Soul, but not for Body and Soul, and Sin.

We are apt to overshoot, in the days that are calm, and to think ourselves far higher, and more strong than we find we be when the trying day is upon us . . . We could not live without such turnings of the hand of God upon us. We should be overgrown with flesh, if we had not our seasonable winter” (Seasonable Counsel, 694). In the days of pain, the Lord showed me how much flesh I still retain –– how prone I am to fear, sadness, worry, agitation, frustration, and doubt. Yet through it all, how wondrously beautiful are the reign of God over sin through the cross and all the gospel fruits that flow from it toward me: forgiveness, reconciliation, life, righteousness, help, true hope, peace, resolute joy, persevering strength, ears to hear the word and a heart to believe it, transformed desires that compel me and my family to follow God.
