I have a lovely leather bound copy of The Valley of Vision that I use for my devotions. But it was a recent purchase and is working well with my Prof Horner bible readings, for which using a proper paper Bible is recommended. Before that I used to use Banner of Truth‘s online devotional as I was reading the Bible on my tablet. Then they updated their website and the prayers went missing for a while, hence the purchase.
But I’ve just found that the prayers are back online. The prayers are in a random order, but are always helpful, and there is a suggested one for the day. And it’s a great way to check them out if you are thinking about getting the book.
