"Therefore, do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own." NIV
"Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof." KJV
Are we fretting over something that cannot be resolved today? Do we become anxious about how things are going to turn out in the future or if things will turn out at all? If we will stay focused on the things we need to take care of today, the things over which we have control, God will take care of tomorrow. He wants us to keep looking to Him and growing in Him while He takes care of the things in our lives that might otherwise keep us in a state of worry.
Heavenly Father, we thank You and praise You that Your are the God who holds tomorrow in His loving hands. Forgive us for doubting and forgetting that. Show us what we need to be doing today and help us take care of those things. Help us leave the rest to You. In Jesus' name we pray, Amen.
