Worry implies that we don't quite trust God is big enough, powerful enough, or loving enough to take care of what's happening in our lives. ~Francis Chan
Worry does not empty tomorrow of its sorrow, it empties today of its strength. ~Corrie Ten Boom
Worry clouds your mind, leads to irrationality, and robs you of peace. Trust God and replace your thoughts.
Verses
Matthew 6:25 - Therefore I tell you, do not be anxious about your life, what you will eat or what you will drink, nor about your body, what you will put on. Is not life more than food, and the body more than clothing?
Psalm 55:22 - Cast your burden on the Lord, / and he will sustain you; / he will never permit / the righteous to be moved.
Romans 12:2 - Do not be conformed to this world,[a] but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
