John Owen
The purpose of our holy and righteous God was to save His church, but their sin could not go unpunished. It was, therefore, necessary that the punishment for that sin be transferred from those who deserved it but could not bear it, to one who did not deserve it but was able to bear it.

The design of gospel tracts is to awaken the minds of men, and to excite in them a sense of their danger and their need of a Savior.
Jonathan Edwards
