To me this is saying, when you burn every bridge and everywhere you turn is a failed opportunity you are probably trying to do too much on your own. Stop following your selfish dreams and destroy that person. “Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come!” II Cor. 5:7
And to me this says, the greatest test of our devotion is when we have nothing left but the things that are the greatest part of ourselves, and yet we will give them in the faith and hope that it is worth it, as well as love of good so that we willingly sacrifice for the glory of God knowing that there may be no other discernible result.
