Praxis, Praxis, Praxis!
Eschatology generates praxis of the new covenant. By praxis we are neither disputing over whether it is by it that we are saved or an expression that we are saved (Luther's idea). Praxis is the symbol that we apply to ourselves for the renewal of not only the world but individual (inner & outer) inconjunction with the inauguration of the Kingdom of God.
It is believing that Christ has brought in His kingdom onto the world and God's judgement is coming; exile is at the door. If praxis is not practiced, exile is inevitable.
