"The peace of God that surpasses all thought will guard their hearts and their mental faculties through Christ Jesus." As this peace comes from God, no one can reach it by himself meditating or trying to improve his personality. In addition, it is so powerful that it "exceeds all thought". In other words, it is imposed on our fears and anxieties, which are often due to a limited or erroneous view of things. Even when we do not see the way out of our problems, the peace of God can give us peace of mind, for we have full confidence in the biblical promise that all our difficulties will soon disappear.

Of course, the only one who can give us a peace like this is God, because for him, "all things are possible" (Mark 10:27). Also, the faith and trust we have in God will keep us from worrying too much. Think, for example, of a child who is lost in the supermarket. As he trusts that his mother will find him, he does not despair. He knows that when he finds him, he will take him in his arms, and everything will return to normal. Likewise, we do not despair, because we know that we can always count on the protection and loving care of Jehovah.
