O God, Grant Firm, Glad, and Grateful Faith

A Lutheran prayer for a robust faith:

O Father and God of all comfort, through your word and Holy Spirit grant us a firm, glad, and grateful faith. By it may we easily overcome this and every trial, and at length realize that what your dear Son Jesus Christ himself says is true: "But take courage; I have conquered the world" (John 16:33). Amen.
