John Milton wrote in Paradise Lost "The mind is its own place, and in itself can make a heaven of hell, a hell of heaven." This verse is so aligned with reality. Several times in my own experience, while nothing external has changed, a change in perspective changes everything experientially--bringing Joy, hope, new energy, or peace--making it easier to breathe.
Our brain necessarily tunes out most incoming information and must interpret what it does allow in through the gate. After allowing some bits in, we make generalizations, assume causation, and generate speculative predictions based on underdetermined evidence. Obviously, a myopic focus that is biased to only pick up negative data points will lead us to construct some ugly meaning from it. We are already inclined towards logical leaps and distortions, and If we only begin with a few gloomy pieces, we can construct a prison of our own making that seems an inescapable reality. Fortunately, the door is locked from the inside and we have the key. If learn to expand our perspective by including additional data points and avoiding cognitive distortions, and when faced with multiple frames (none of which can be proven conclusively) we side with a frame that brings life, our life can improve significantly.
Anyhow, I am glad a Christian wrote a book on the power of reframing. The second chapter was absolute gold, the rest of the book was fine. This topic is something that the Apostle Paul understood, Jesus grasped and quite a lot of scripture communicates. Pointing out ways the Bible attempts to shape us by influencing how we frame our experiences is a good way to use scripture. Here we have a message that is true and can withstand scrutiny and is something that will not need to be later deconstructed. We need more messages and more books on this topic!
