「上帝究竟在哪裡？」這是當代神學一直面臨的基本信仰問題。面對信徒的詰問和疑惑，面對世人的絕望和恐懼，當代神學該為上帝的存在進行怎樣的辯護？莫爾特曼和默茨等为代表的政治神學正好開闢了當代神學的一條辯護路徑：即以《聖經》為根基，以末世為中心，以政治為應用，通過重新詮釋末世論來重申「未來性神學」，從而擺脫「超越性神學」和「臨在性神學」的信仰困境，依靠「人類的希望」和「上帝的應許」從而釋放出基督教信仰所固有的解放力量。在末世論的希望詮釋學中，重新將「希望」作為基督教信仰的本質和基礎，為推進社會正義找到「希望的動力」。本文認為當代的新政治神學不僅通過「希望神學」還原了基督教信仰的末世主題，而且憑藉「實踐優先」和「榮耀國度」強化了基督教信仰的正義訴求。這種當代政治神學以其全新視角對於末世論的詮釋，充分彰顯了基督教神學的批判向度和解放作用。從某種意義上說，這種當代政治神學旨在恢復基督教與政治訴求之間的天然聯繫，由此為人類追求正義的事業提供一個強有力的精神支柱。

“Where is God?” This is fundamental faith question that Christian theology had to answer it in today. Could Christian theologian defend God in the face of Christian skepticism and mankind’s holocaust? In some sense, political theologies of Jurgen Moltmann and J.B.Metz open justly a road for us toward the kingdom of God. According to them, Bible is the root of Christian faith, eschatology is the kernel of Christian faith, justice is the practice of Christian faith. In order to resolve the faith crisis of theology of transcendence and theology of immanence, we must revive theology of future, and release the revolutionary strength in Christian faith by promise of God and hope of mankind. In their eschatological interpretation of political theology, hope is the essence of Christian faith, and the force of social progress. This article tries to show that theology of hope of J. Moltmann and J.B.Metz reveal not only the eschatological meaning, and also strengthen the appeal of justice in Christian faith. Theology of hope could build the natural connect between Christianity and political struggles, and indicate a spiritual force of mankind’s liberation.
