This window depicts the Angel of the Open Book (also called the Angel of Life) with a torch in one hand and the Book of Remembrance in the other. The "Open Book" is the Book of Life that is mentioned in Revelation, the final book in the Bible.
"The one who is victorious will, like them, be dressed in white. I will never blot out the name of that person from the Book of Life, but will acknowledge that name before my Father and his angels. Whoever has ears, let them hear what the Spirit says to the churches."
Those who have put their trust and faith in Jesus Christ as Lord of their life and their Savior from sin and death will have their names written in the Book of Life. Inclusion means that when you die you will not perish, but receive eternal life. Through belief in Jesus and living life as he did, you can be certain that your name is written in the Heavenly Book of Life.
(White garments are an artistic symbolic way of designating a person who is washed clean in the blood of Jesus through faith, whose sins are forgiven by the death of Jesus on the cross.)
(There is a nearly identical window in the Pitts Chapel Unified Free Will Baptist Church in New Haven, CT. An 1898 newspaper article about the windows refers to the window as the Angel of Life. The inscription at the top of the Pitts Chapel window says, "He that believeth in Me, though he were dead, yet shall he live.")
The Craig Window was a gift of Mrs. A.M. Davidson in memory of Neville B. Craig (1787-1863) and Jane Anne Fulton (1780-1852).
