Dr. Alex Bunn and Dr. David Randall of the Christian Medical Fellowship analyzed 1,200 studies and 400 reviews. They found that having faith was linked to better protection from getting physical illnesses and increased ability to cope with sickness.

Furthermore, enhanced mental well-being was reported. One study involving over 20,000 American adults showed seven years higher life expectancy among regular church goers.

Our thankfulness, Dr. Alex Bunn and Dr. David Randall, for highlighting some of the advantages of having faith in the Divine. May all people flourish in body, mind, and spirit.
