The phrase “Sufficient unto the day is the evil thereof” (Matthew 6:34, KJV) comes at the end of Jesus’ teaching on worry in the Sermon on the Mount. In simple terms, Jesus is saying that each day has enough trouble of its own, so we should not borrow tomorrow’s anxieties and drag them into today. Every day carries its own challenges and responsibilities, and God calls us to face today’s difficulties with today’s faith.
Jesus’ instruction is deeply practical: focus on the present. The Greek word translated “take no thought” or “be not anxious” is merimnao, meaning to be distracted or to have a divided mind. Worry pulls our attention away from the responsibilities God has placed in front of us and scatters our energy across imagined future problems. Jesus urges us to “be present in today,” to stop catastrophizing about what might happen tomorrow, and to trust that God will meet us in the future when we get there.
This teaching rests on trust in divine providence. Jesus reminds us that God feeds the birds and clothes the lilies—God is fully aware of our needs and oversees even the smallest details of our lives. We do not need to fear tomorrow’s “evil” (meaning trouble or pressure), because God is already in our tomorrows. When we arrive at tomorrow’s experiences, strength and guidance needed for that day will be available. Our task is to seek first God’s kingdom and righteousness, trusting that He will provide what is necessary.
In a deeper spiritual sense, “the evil of the day” refers not only to moral wickedness but to the trials and difficulties that come with living in a fallen world. God permits a daily portion of these experiences for the discipline and development of His people. Jesus’ command does not excuse carelessness or laziness—we are still to be diligent and responsible. Rather, he forbids the kind of anxious care that implies a lack of confidence in God’s promises. We are to do our part today and trust God’s overruling for tomorrow.
God wisely limits the amount of trial He allows in a single day because He knows our human limitations. Each day contains enough spiritual warfare, emotional strain and practical responsibility without adding imagined future catastrophes on top of it. Worrying about tomorrow wastes the strength God has given us for today’s tasks. Divine help is not promised far in advance; it is promised “in time of need.” When tomorrow comes, God will provide tomorrow’s grace.
This principle becomes especially important in difficult or uncertain times. Scripture describes the present age as an “evil day,” full of testing and pressure. Jesus’ words teach believers to watch and trust rather than being overwhelmed by fear of future restrictions or hardships. Our responsibility is to guard our hearts today, walk faithfully today, and settle our accounts with God today.
In short, Jesus teaches that today’s troubles are enough for today, and tomorrow’s troubles belong to God until tomorrow arrives. Our calling is daily faithfulness, daily trust and daily reliance on the Father through Jesus, who knows our needs before we ask.
