Gospel truth is the only root whereon gospel holiness will grow. If any worm corrode, or any other corrupting accident befall it, the fruit will quickly fade and decay. It is impossible to maintain the power of godliness where the doctrine from whence it springs is unknown, corrupted, or despised. And, on the other side, where men are weary of holiness, they will not long give entertainment to the truth; for as to their desires and affections, they will find it not only useless but troublesome.
