One of the books I'm reading right now is Holding on to your faith even...When God Doesn't Make Sense by Dr. James Dobson.
What stood out to me today is how God's presence is not inconstant. It is our perception of Him that comes and goes. We cannot rely on our emotions, as they often change with the wind. His Word, His promises are always true and right and unfailing!
Another encouraging thought for today-- we must never forget that this separation is temporary.
