Recently one that I love very much became gravely ill. Her heart was under terrific stress and acute pain, a coronary thrombosis (heart attach). Fear came into my mind.
"Casting all your care upon him; for he careth for you."-- 1 Peter 5:7 (KJV)
"Fear" is not from God;
"For God did not give us a spirit of timidity (fear), but a spirit of power, of love and of self-discipline." (2 Timothy 1:7--NIV).
So I put FEAR aside; I called 911. Caring EMTs came and stabilized my loved one and transported her to the hospital. The hospital and the doctors, and three stints later -- rest 3 days in ICU and several more days of rest at home - and much better. Thanks to modern medicine.
But more importantly the real thanks are to God Almighty! GOD heals the person's body, mind, and spirit -- Total healing! The Praise is to the Lord.
