A prayer before writing or teaching from Christina Rossetti (1830-1894):

Lord Jesus Merciful and Patient, grant us grace, I beseech Thee, ever to teach in a teachable spirit; learning along with those we teach, and learning from them whenever Thou so pleasest. Word of God, speak to us, speak by us, what Thou wilt. Wisdom of God, instruct us, instruct by us if and whom Thou wilt. Eternal Truth, reveal Thyself to us, reveal Thyself by us, in whatsoever measure Thou wilt.
