Leave it to Unbelievers

Malaria is a rabid killer on the continent of Africa. It kills millions of children. Bill and Malinda Gates donated 700 million dollars to a research company that has now come up with a vaccine. The initial test results are extremely encouraging, with an almost 50% reduction. So all it took was additional funding?
Well at least the American church can claim ornate auditoriums, high tech sound systems, exorbitant salaries, Christian cruises, and all sorts of expenditures including vast amounts spent on advertisement. But what about the malaria ravaged children of Africa?
We can leave that stuff to unbelievers like Bill Gates.
