A key in Christian's bosom, called Promise, opens any lock in Doubting Castle Then Christian pulled it out of his bosom, and began to try at the Dungeon door, whose bolt (as he turned the Key) gave back, and the door flew open with ease, and Christian and Hopeful both came out. Then he went to the outward door that leads into the Castle-yard, and with his Key opened that door also. After he went to the iron Gate, for that must be opened too, but that Lock went damnable hard, yet the Key did open it. Then they thrust open the Gate to make their escape with speed; but that Gate as it opened made such a creaking, that it waked Giant Despair, who hastily rising to pursue his Prisoners, felt his limbs to fail, for his Fits took him again, so that he could by no means go after them. Then they went on, and came to the King's High-way again, and so were safe, because they were out of his jurisdiction {294} Now, when they were over the stile, they began to contrive with themselves what they should do at that stile to prevent those that should come after from falling into the hands of Giant Despair. So they consented to erect there a pillar, and to engrave upon the side thereof this sentence--"Over this stile is the way to Doubting Castle, which is kept by Giant Despair, who despiseth the King of the Celestial Country, and seeks to destroy his holy pilgrims." Many, therefore, that followed after read what was written, and escaped the danger. This done, they sang as follows:-- Out of the way we went, and then we found What 'twas to tread upon forbidden ground; And let them that come after have a care, Lest heedlessness makes them, as we, to fare. Lest they for trespassing his prisoners are, Whose castle's Doubting, and whose name's Despair. {295} They went then till they came to the Delectable Mountains, which mountains belong to the Lord of that hill of which we have spoken before; so they went up to the mountains, to behold the gardens and orchards, the vineyards and fountains of water; where also they drank and washed themselves, and did freely eat of the vineyards. Now there were on the tops of these mountains Shepherds feeding their flocks, and they stood by the highway side. The Pilgrims therefore went to them, and leaning upon their staves, (as is common with weary pilgrims when they stand to talk with any by the way), they asked, Whose Delectable Mountains are these? And whose be the sheep that feed upon them? Mountains delectable they now ascend, Where Shepherds be, which to them do commend Alluring things, and things that cautious are, Pilgrims are steady kept by faith and fear. {296} SHEP. These mountains are Immanuel's Land, and they are within sight of his city; and the sheep also are his, and he laid down his life for them. [John 10:11] CHR. Is this the way to the Celestial City? SHEP. You are just in your way. CHR. How far is it thither? SHEP. Too far for any but those that shall get thither indeed.
