So do not worry or be anxious about tomorrow, for tomorrow will have worries and anxieties of its own. Sufficient for each day is its own trouble. (Matthew 6:34 AMP)
Did you ever have nights when you found a hard time to sleep? When you do, most of the time is when you are bothered with troubles that might come along with the incoming day or with the day after. It makes us worry and fear to live another day because it might turn out to be not so pleasing to us and might result to a worse situation. Do not fear my brothers and sisters, the Lord is with you. Cast all your worries and anxieties on Him. He cares for you so much that He wants you to face the challenges of your everyday life with courage and confidence in Him. It is the problem of the coming day how it would give you a hard time. But worry not, God sees what is ahead, and He will equip you with everything you need to overcome all of it.
