God, in all his works, has proceeded on a system; there is a beautiful connexion and harmony in every thing which he has wrought…Now if God proceeds on system, it may be expected that the Scriptures, being a transcript of his mind, should contain a system; and if we would study them to purpose, it must be so as to discover what the system is.
Andrew Fuller, The Complete Works of Andrew Fuller, 1:165
