This heavenly light of truth

(John Angell James)

"All Scripture is inspired by God, and is useful for
 teaching, rebuking, correcting and training in
 righteousness, so that the man of God may be
 thoroughly equipped for every good work."
    2 Timothy 3:16-17
The doctrines of Scripture are facts, which involve
corresponding emotions and principles of action,
and must, from their very nature, if believed, be 
operative upon the heart and the life.

If the doctrines of Scripture . . .
  exert no godly influence,
  carry with them no practical weight,
  exert no moral power,
they are not truly believed.
The doctrines of Scripture are at once . . .
  the source of consolation, and
  the means of sanctification.
The doctrines of Scripture . . .
  come into the mind as knowledge,
  produce peace and love in the heart,
  and spread the beauties of holiness
over the character and conduct.
The doctrines of Scripture are light; and like the
rays of the sun, they sustain life at the root of
the vine, and produce fruit on its branches.

This heavenly light of truth gives . . .
  spiritual vitality to the soul,
  and holy conduct to the life.

"For our gospel came to you not simply with
 words, but also with power, with the Holy
 Spirit and with deep conviction." 1 Thes. 1:5

"Sanctify them by the truth; Your Word is truth."
    John 17:17
