“Past” is a noun that refers to history, as in these converse statements: “he had a rich past,” or “he regretted his past.” Whether memorable or regrettable, we cannot live in the past: what’s passed is in the past.
But having become the recipient of “new things” in Christ: behold I make all things new (Rev. 21:5), we must be diligent and deliberate in leaving the past behind—every day. This is the “dying to live” principle by which I have sought to live my life, however ineffectively. Perhaps it is because I have so many unspeakable things in my past that I have made every effort to “die” to what-was in order to “live” to what-is.
Because my failures in this pursuit far outweighed my successes, I relish the day when the truth will be reality—the day when I will no longer be “dying to live.” I will have left the past behind forever.
