Eschatology drives discipleship. If we want to have a discipleship response as we see in the New Testament, we have to preach the same vision of the future that Jesus preached: a vision that revolves around the Day of the LORD. This vision informs our vision of what God is doing, it strengthens us through trials, it informs how we ought to live in light of our destiny, and it motivates us to self-denial with that end in mind. - John Harrigan, Eschatology Drives Discipleship
