Of what value is all our knowledge of truth?

(Octavius Winslow, "Evening Thoughts")

Of what value is all our knowledge of truth . . .
  if it does not lead us to Jesus;
  if it does not expand our views of His glory;
  if it does not conform our minds to His image;
  if it does not increase our love to Him,
  if it does not quicken our obedience to His commands,
  if it does not quicken our zeal for His cause;
  if it does not mature us, by a progressive holiness,
for the enjoyment of His beatific presence?
