In this manual of Christian faith, Scottish minister and author Horatius Bonar investigates the words of God with respect to humanity and the human condition.

Throughout the Bible, God's words are relayed by messengers and prophets. In the various dialogues received from the Lord, the views of the divine regarding His creation mankind are revealed. It is through these descriptions that Horatius Bonar commences his investigation of God's correspondences with man; gradually, the character of the Lord is revealed, and his intentions and purposes for humanity unveiled.

The event which most richly demonstrates God's connection with human beings is the birth and life of Jesus Christ. Bonar notes the significance of the blood shed by Jesus is connected with the blood shed by Abel during the Book of Genesis. Furthermore the teachings and sermons of Christ reveal much about God's views on mankind and its destiny. The importance of man acknowledging his own fallibility and flaws - of discarding his insensibility - is expounded upon.

Overall, Horatius Bonar presents an impressive primer on what Christianity means in the context of the Creator and man's place on the Earthly plane.
