As twenty-first-century Christians, we must relate to the world, but the question is, how do we relate to it? Some Christians are scared, others are simply bewildered, and still others capitulate to the spirit of the age. In Passing Through: Pilgrim Life in the Wilderness, Pastor Jeremy Walker presents the biblical perspective that Christians are pilgrims passing through this fallen world who must cultivate the spirit of holy separation alongside holy engagement as they serve Christ in all their interactions. Unless we embrace this identity, we will lose our way. Reminding us that we need “the Word of God as our map and the Spirit of Christ as our compass,” here are principles for holy engagement with the world and separation from it for pilgrims on their way home, seeking to glorify the God of their salvation every step of the way.
