It belongs to prayer, but it is not exhausted by it not identical with it. In contemplation, complaining ceases. The heart opens itself for reception. We become free from our self-serving desires and also from the ideals that we have for others, for our children, or for society. We listen and wait for the voice of God. Prayers without hearing and speaking with God, without waiting for God, do not lead very far. For this reason contemplation is important. It is not in itself practical, it is utterly ‘impractical.’ Yet our meditation on Christ’s passion and our contemplation of His spiritual presence can alter our praxis more radically than all the other alternatives which even the most active among us can conceive. In contemplation we ourselves become another. We experience the conversion of our life and live the pains and joys of our rebirth.
Jurgen Moltmann, 1978.
