(Matthew 6:34 - KJV) "Sufficient unto the day is the evil thereof."
I was reminded of this a couple of times this morning. We have problems today and then we begin to worry about how we will cope with tomorrow. It grows into a snowball of trouble.
(Matthew 6:34 - NKJV) "Sufficient for the day is its own trouble."
Don't we have enough to deal with today? How do we know that we will even make it to tomorrow? At the very least things may change completely before tomorrow.
(Matthew 6:34 - NASB) "Each day has enough trouble of its own."
Just focus on today's tasks and don't burden yourself with things you can't do anything about. There is a reason that Alcoholics Anonymous has "One Day At A Time" as a slogan.
(Matthew 6:34 - NIV) "Therefore do not worry about tomorrow, for tomorrow will worry about its own things. Sufficient for the day is its own trouble."
This is not to say we should be clueless and careless. It means that we can trust God. The future is in His hands. We are in His hands. He will deal with us faithfully in the future according to His unfailing love and mercy. He will provide what we need then, just like He provided yesterday.
(Hebrews 13:8) Jesus Christ is the same yesterday, today, and forever.
