Mental illness is as real as diabetes. Christians should (of course pray), but encourage people with persistent depression (which could be a sign of a larger mental health issue) to seek professional medical help.
Sometimes prayer and positive thinking are not the answer (or only answer). God, in His sovereignty, also gave us doctors and medicine.
Many churches need to address mental health issues. The Church believed the world was scientifically the center of the universe for far too long. May we be ahead of the curve on such things!
