As we continue looking for what the Lord would have us do to prepare for His coming we see His counsel to be made clean, (notice the word there is clean not perfect.) And to leave Babylon behind and "look not back." I love the emphasis on not looking back to our sins and lamenting what we feel like they can offer us, rather we look forward to the future with faith in what the Lord can make of us!
