I once heard someone say, "good things fail so great things can happen". How true. The Apostle Paul understood how critical it was to forget.
When we think of "forgetting", we my sometimes envision a negative implication, because, who wants to be forgetful? It behooves us then to consider how remembering the past can negatively impact or influence our present as well as our future. This holds true for good times and bad times, unless of course we are thinking on what is profitable and brings glory to God, Philippians 4:8. I believe that when Paul the Apostle encouraged us to forget the past, he was leaning more to the art of forgiveness.
In the book of Philippians 3:4-6, Paul recounts his achievements. He speaks of his own righteousness and gains. However, at the end of the trail, in verses 7-11, he concluded all to be dung, nothing, loss, so that he might attain unto what is far better: the knowledge, righteousness, fellowship, and power of Christ, and ultimately, resurrection from death. But how will Paul attain to this excellency? Verses 13-14 reveals Paul's strategy: he forgets the past, and he keeps on forgetting the past, and adding to that, he reaches for the future; the prize before him, so that he might attain unto the image of Christ. That's the goal.
Here's something that might pique your interest: in Romans 8:38-39 the Apostle Paul outlines a number of things that would not be able to separate us from the love of God. I find it interesting that he mentioned the present and the future, but not the past. Something to think about.
Whatever your past holds, forgive it, forget it, let it go. And keep in mind, life has little to do with time and far more to do with eternity, so let's look to the future. Let's hear what Lauren Daigle has to say in this inspiring piece. "Trust in You"
