Jürgen Moltmann:
As a result of this hope in God’s future, this present world becomes free in believing eyes from all attempts at self-redemption or self-production through labor, and it becomes open for loving, ministering self-expenditure in the interests of a humanizing of conditions and in the interests of the realization of justice in the light of the coming justice of God. This means, however, that the hope of resurrection must bring about a new understanding of the world. This world is not the heaven of self-realization, as it as said to be in Idealism. This world is not the hell of self-estrangement, as it is said to be in romanticist and existentialist writing. The world is not yet finished, but is understood as engaged in a history. It is therefore the world of possibilities, the world in which we can serve the future, promised truth and righteousness and peace. This is an age of diaspora, of sowing in hope, of self-surrender and sacrifice, for it is an age which stands within the horizon of a new future. Thus self-expenditure in this world, day-to-day love in hope, becomes possible and becomes human within that horizon of expectation which transcends this world. The glory of self-realization and the misery of self-estrangement alike arise from hopelessness in a world of lost horizons. To disclose to it the horizon of the future of the crucified Christ is the task of the Christian church.
