When we think of being careful we tend to associate the idea of being cautious and avoiding risk. However, when Peter penned these words he had a different intent, and yes I know that Peter didn’t write in English. Peter is actually telling us not to be full of care of worry but instead to trust God and let him know our cares and concerns through prayer. Also notice that he never mentions that God will be our magic Genie in a bottle and grant every frivolous request, but instead promises the peace of God that surpasses our understanding. Peace when it doesn’t make sense, calm when others find none, comfort when the world goes crazy. Sign me up!
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. Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
