“Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus” (Philippians 4:6,7).
With today’s Scripture in our hearts and minds, those hearts and minds are guarded!
Second Timothy 3:12 tells us: “Yea, and all that will live godly in Christ Jesus shall suffer persecution.” Acts 14:22 says of Paul and Barnabas: “Confirming the souls of the disciples, and exhorting them to continue in the faith, and that we must through much tribulation enter into the kingdom of God.” Whenever we purpose to live godly in Christ Jesus, we will suffer persecution. This is a fact of Christian doctrine, even though the popular idea in “churchianity” today is that God wants to remove all of our problems (or remove us from them).
If Satan cannot cause us to change or pervert the doctrine that we teach and preach, then he will do his best in using whatever he can to stop us from teaching and preaching. In other words, after unsuccessfully attacking the message, he proceeds to attack the messenger. Should we worry? Should that bother us? Should we fret? Should that discourage us from even trying to do right at all? No, dear friends, no! Today’s Scripture reminds us not to be “careful”—we should not be anxious, worrisome, taking thought of it.
In our circumstances, regardless of our circumstances, we are “by prayer and supplication with thanksgiving [to] let [our] requests be made known unto God.” Why? Prayer is not designed to change our circumstances, as commonly thought, but it is to change us within as we endure those circumstances. “The peace of God, which passeth understanding, shall keep [our] hearts and minds through Christ Jesus.” The idea here with “keep” is guard. Satan is out to harm us internally (mentally and spiritually). Thankfully, God has given us the ability—through His written Word and us praying according to it rightly divided—so we can ward off his attacks. Ultimately, it will cause us to think of our circumstances the way God Himself does. source
