Book excerpt: World missions needs a fully biblical ethos. This is the contention of the editors of and contributors to World Mission, a series of essays aimed at reforming popular approaches to missions. In the first set of essays, contributors develop a biblical theology of world missions from both the Old and New Testaments, arguing that the theology of each must stand in the foreground of missions, not recede into the background. In the second, they unfold the Great Commission in sequence, detailing how it determines the biblical strategy of all mission enterprises. Finally, they treat current issues in world missions from the perspective of the sufficiency of Scripture. Altogether, this book aims to reform missions to be thoroughlyâ€"not just foundationallyâ€"biblical, a needed correction even among the sincerest missionaries.
