Trouble refers to the challenges that come with living in a world under God’s curse (Genesis 3:14–19). Until the return of Christ, there will be hardship, suffering, and disease. Christians are not free from these problems (Matthew 5:3–12). Rather than worrying about future problems, disciples should concern themselves with the challenges that are brought by each day. They should focus on those things about which they can actually do something, rather than worrying about things over which they have no control.
34 Ne vous inquiétez donc pas du lendemain; car le lendemain aura soin de lui-même. A chaque jour suffit sa peine.
