Unless the Spirit…

We must realize that the grace of the Holy Spirit is necessary not only for those who teach but also for those who are taught. Unless the Spirit is present in the heart of the listener, the teacher is wasting his breath. Unless there is a teacher within us, the teacher without works in a vacuum.
–Rabanus Maurus (c.780-856)

Without passion in their hearts…

Those who believe that they believe in God, but without passion in their hearts, without anguish of mind, without uncertainty, without doubt, without an element of despair even in their consolation, believe only in the God idea, not in God himself.
–Miguel de Unamuno (1864-1936)
