What brings us to perfection? An ingrained faith in God, the ‘faith that makes real the things for which we hope’ (Heb. 11:1), the faith whereby Abel offered to God a better sacrifice than Cain and was commended as righteous (cf. Heb 11:4). It is such faith that fills those assiduous in the search for truth with great aspiration for the exalted gifts of God, and leads them to the spiritual knowledge of created beings; and it pours into their hearts the inexhaustible treasures of the Spirit.
St. Nikitas Stithatos
