I moved some photos from my camera to my computer the other day. As I did so, I made some adjustments. I erased some which were too out of focus. I used the auto-adjust button for some to correct exposure issues while I used the colour or exposure buttons for others. A couple of the pictures looked much better with a filter of one sort or another. There was a time, not so very long ago, when I would have had to actually take many versions of the picture with actual changes on flash or actual filters. I put four versions of the same picture in this post to illustrate the differences wich are possible.
What you see depends on the filters you use. As Christians we read the Old Testament with the lens of the New. We can work to understand the Old Testament within its historical perspective, but in the end our understanding is coloured by our knowledge of the life and ministry of Christ and the ultimate grace of God. When we read disturbing things like entire nations being wiped out at the direction of God we are simultaneously confused that such a thing would be possible from a God of love, and reassured by the knowledge that in the end salvation is made available to all of us who believe in the Father, the Son, the Holy Spirit, the holy Catholic and Apostolic church, the forgiveness of sins, the resurrection of the body and the life everlasting.
