It is up to us to add labors to labors in order to ‘go from strength to strength’ (Ps. 83:7), and to come ‘to the measure of the stature of the fullness of Christ’ (Eph. 4:13), so that the words of the Lord may be fulfilled in us: ‘But they who wait upon the Lord shall renew their strength; they shall grow wings like eagles; and they shall run and not be weary; they shall walk and not faint’ (Isa. 40:31). Only then will our present joy (which now visits us little and briefly) appear in all its fullness; and no one will take it from us, for we shall be filled to overflowing with inexplicable heavenly delights.
St. Seraphim of Sarov
