It is impossible to conceive of a praying man, therefore, as destitute of grace. If he prays, really prays, he draws near to God with heart open for grace, humbly depending on Him for its gift. And he certainly receives it. To say, Behold he prayeth! is equivalent, then, to saying, Behold a man in Christ! -B.B. Warfield, Prayer as a Means of Grace
