Although this faith may be different in degrees, and may be weak or strong, nevertheless is even at its very weakest in an entirely different class and has a different nature (like other aspects of saving grace) from the kind of faith and common grace which is possessed by temporary believers. Therefore, though it may be frequently assailed and weakened, it gets the victory, growing up in many to the attainment of a full assurance through Christ, who is both the author and finisher of our faith.
