For the most part, worry is wrong. Jesus teaches this during His sermon on the mount. Listen to His words when He says, “Therefore I say to you, do not worry about your life, what you will eat or what you will drink; nor about your body, what you will put on. Is not life more than food and the body more than clothing?” (Mt 6.25ff)
Jesus plainly shows us that it is wrong to have great anxiety over material things such as what we will eat or wear. Worry about the mundane things of this earth is useless because it changes nothing and worry is faithless because it reflects a lack of confidence that God can and will take care of us.
With that being said, is there ever a healthy kind of worry? Yes, actually there is, although we might choose to use words like concern or care in place of worry. Take a look at what the apostle Paul says, “I hope in the Lord Jesus to send Timothy to you soon, so that I too may be cheered by news of you. For I have no one like him, who will be genuinely concerned for your welfare.” (Phil 2.19-20)
Both Paul and Timothy are greatly concerned, even worried, about their brethren in Philippi. They were evidently facing some adversity that tested their Christian conduct (Phil 2.27-30) which could damage them spiritually. Paul was determined to send Timothy to help them due to Timothy’s deep love and sincere care for the Philippians. I believe we can say that both of these men were vitally concerned, or even worried, about the spiritual welfare of their fellow Christians.
This is not the only time Paul would feel great anxiety in his heart concerning all of the churches, to the Corinthians he said, “And, apart from other things, there is the daily pressure on me of my anxiety for all the churches.” (2 Cor 11.28)
Paul was not worried about how many times he would be put in jail, beaten, or shipwrecked, these are all worldly things. What concerned him was humbleness, teaching Christ, and standing up against false teaching. He felt great concern, anxiety, and yes worry, for God’s children who faced the kind of adversity that could weaken the spirit and their bond with God.
So we ought to try to conquer our fretfulness over the mundane, temporal matters of our earthly life, while realizing that there is a legitimate place for true concern and care for the spiritual welfare of others.
