It occurred to me that when you are driving a care your vision is both to the front and to the rear. As we move down the highway we primarily keep our eyes to the front to maintain proper lane position and manage distance to vehicles ahead, as well as to look for signs and exits. But we also keep an eye on what is happening behind us, especially to monitor the closeness of following vehicles. And when we are maneuvering out of many parking areas the rear view can be more important than the forward view, especially if we are backing. As we move through life we are looking forward a great deal with focus on the current day and the upcoming events just ahead, or down the road a bit. But we get perspective from looking back as well, drawing on wisdom and lessons learned from our past. And, when it comes to our relationship with the Lord, we have built the faith walk that we experience from God's faithfulness in the past, and His real intervention in our lives. This helps us as we move into the "unknown" of the road ahead. We do a lot of "look back" as we read the Bible and the Old Testament provides colorful illustrations that are distilled as life lessons in the New Testament.
We seem to need the "look back" to set perspective for the "look ahead".
Psalm 77:11 I will remember the works of the Lord; surely I will remember your wonders of old.
