That is a strong sentence because it is opposite of the way most people, even Christians, live their lives. Most people think "Oh my, if I would have only..." or "What a shame, if I could have just..." or "I'm so sad because I should have ...."
Because of these thoughts, many people live lives full of regret. I want to show you from Scripture that there's no place for regretful thoughts in the life of a Christ-believer. Stuff happens; but God happens to be over our happenstances. He promises to those of us who've embraced His Son that He will turn all things, even our mistakes, into ultimate good for His eternal glory. Let me show you a powerful example of this Romans 8:28 principle.
There's a verse in Acts 26:31 that many Christians pass quickly over without giving it serious thought. I'll quote the verse in just a moment, but let me set the context. Paul has been accused of blasphemy for bringing Gentiles into the Temple, a capital offense among the Jews. He stands trial before Felix in Caesarea on charges of inciting riots, being the leader of a sect of people who follow "the Nazarene," and of desecrating the Temple (see Acts 24:5-8).
Eventually King Agrippa, the Roman puppet king over the Jews, assists Felix during Paul's trial because Paul had appealed to Rome as a Roman citizen, being from the Roman city of Tarsus. Paul convincingly argues to both Felix and Agrippa that he is doing nothing contrary to the Jewish religion and that he "worships the God of our fathers" (Acts 24:14-15) and is innocent of all charges. Both Felix and Agrippa believe Paul is innocent of blasphemy charges, but in Acts 26:31 Agrippa makes a stunning statement:
"This man could have been set free if he had not appealed to Caesar"
Ouch. Don't gloss over that statement lightly. Paul, in chains and in prison for two years, facing capital charges, could have been set free, if he had not...
Put yourself in Paul's shoes. What do you think he's thinking at that moment? Prison is not fun. Two years is a long time. This episode of arrest, two-year imprisonment, and ultimate trial in Caesarea occured after Paul's third missionary journey. While Paul had been waiting for his hearing before Festus and Agrippa, there had not many people to whom Paul could minister the gospel. Paul had known what it meant to be a success in Christ's Kingdom, but for two years he's been a prisoner in chains. Surely Paul wanted out of prison, right? Certainly Paul wanted to go on a fourth missionary trip, yes? If Paul is like us, he had to have believed being in prison was far worse than being out of prison. Wouldn't you? I think so.
Yet Paul hears, "You could have been set free if you had not...." At that moment, I'm sure the enemy launched the fiery darts of deep disappointment toward Paul. Regret had to have been assaulting the gate of Paul's heart. It's a little like you hearing, "You could have....if you had not...", or you thinking, "I should have...but I did not..." and all the feelings that come your way during those occasions of regret.
But let me remind you what happened next to Paul. He is sent to Rome and placed in custody there. While in prison he shares Christ with both his fellow inmates and officials from Caesar's court. He also writes letters that we know as the Prison Epistles— Ephesians, Colossians, Philemon, and Philippians. It's possible that the initial infiltration of the gospel into the Legion of Thunder and Caesar's court began with Paul's imprisonment in Rome. It is certain that all the encouragement we've received from the Prison Epistles can be traced to Paul's imprisonment in Rome.
More precisely, all the good that's come our way through reading Paul's epistles can be traced back to a day of potentially great disappointment for Paul.
He coulda, woulda, shoulda been free from prison after two years, but he appealed to Rome. Again, I imagine Paul initially thought he had messed up. However, we learn from Paul's life the Romans 8:28 principle that God always has other plans for us, much better plans, even when we think we've screwed-up big time.
Regret is a poison pill. It darkens the soul and deadens the senses. It's a fog that descends and clouds your surroundings, so that you have difficulty engaging what's in front of you, enjoying what's around you, and escaping what's behind you.
Regret has no place in the Christian life because our good Father turns around everything in our lives for our good. Everything. Everything includes our mistakes, our sins, our tragedies, our screw-ups, our "wrong" decisions, and everything else that leads us to "coulda, shoulda, woulda" thinking.
When your mind begins to be filled with regret, squash it and get rid of it like you do a roach found in your kitchen. It's an invader; it's an intruder in a space where it does not belong. God takes all of our couldas, wouldas and shouldas and works them for our ultimate good and His ultimate glory. That's the kind of Heavenly Father we have; He is all-powerful and always good.
Believe it and live it.
