I just read this excellent summary of Luke’s view of salvation in Joel B. Green’s The Gospel of Luke. NICNT. Grand Rapids: Eerdmans, 1997. Take a look!
Salvation is neither ethereal nor merely future, but embraces life in the present, restoring the integrity of human life, revitalizing human communities, setting the cosmos in order, and commissioning the community of God’s people to put God’s grace into practice among themselves and toward ever-widening circles of others. Their Third Evangelist [i.e. the author of Luke’s Gospel] knows nothing of such dichotomies as those sometimes drawn between social and spiritual or individual and communal. Salvation embraces the totality of embodied life, including its social, economic, and political concerns. For Luke, the God of Israel is the Great Benefactor whose redemptive purpose is manifest in the career of Jesus, whose message is that this benefaction enables and inspires new ways for living in the world. (pp. 24–25)
