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,” Pastor Walker clearly presents 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.“From Hebrew prophet to the New Testament sage who wrote Hebrews, from the North African theologian Augustine to the French Reformer John Calvin, God’s people have confessed that they are a pilgrim people. And here, in a brief compass, we find the same truth about our identity in Christ in this world: we are aliens and strangers, those who are 'passing through.' A timely reminder of who the Christian truly is." — Michael A. G. Haykin, professor of church history and biblical spirituality, The Southern Baptist Theological Seminary
