A prayer of Soren Kierkegaard (1813–1855)

O Lord, calm the waves of this heart; calm its tempests. Calm yourself, O my soul, so that the divine can act in you. Calm yourself, O my soul, so that God is able to repose in you, so that his peace may cover you. Yes, father in heaven, often have we found that the world cannot give us peace, O but make us feel that you are able to give peace; let us know the truth of your promise: that the whole world may not be able to take away your peace.
