“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?” (Matthew 6:25, ESV)
Anxiety is real. But it has no place in the life of a believer.
God is not slack in his care for his children. He knows what we need before we even ask.
To be anxious about life or body is to doubt God’s goodness, or doubt God’s ability.
Both constitute disbelief.
