It is absolutely essential for the soul to rejoice in the Lord.

Do not worry anymore; the Lord is quite near, He is close. It is absolutely essential for the soul to rejoice in the Lord, to leave all worries behind, at least at the moment when one dedicates oneself to God. That is why Saint Paul says: do not worry, because the Lord is near, He is close to us, meaning in the deepest depths of our being, when He finds us within ourselves...

(Master Eckhart OP /1260–1327/, Sermon Gaudete in Domino)
