In the Presence of Angels by Andrea Garrison is a very short and easy to read volume.
The book tells about Andrea’s family history. And it includes her reflects on Emanuel Swedenborg.
I don’t agree with much of Swedenborg’s theological and philosophical views as they are outside the realm of orthodox Christianity.
Since most of my blog readers are Christians, I think you’ll find this book a quick and easy read. Some parts are inspiring. However, you will also find much that you won’t agree with.
You can investigate more on Amazon and on the Patheos Book Club.
With respect to angels, they are certainly real. The book of Hebrews talks about them and we see them all over the Gospels. One of the most interesting texts in all the NT is where the writer of Hebrews exhorts God’s people to be hospitable to others, for in so doing, they may be “entertaining angels unaware.”
Have you ever had such an experience?
