Cool. So the adventists in Loma Linda benefit from their beliefs right here on earth. I have a notion that positive religiosity, not just adventism, does a number on quality of life. It plugs a need for reassurance. Which allows the native to worry less.
But looking at the world in general, it looks like the wealth of a community tends to be a better predictor for longevity.
Sure, one could make that argument. Three models of longevity may be considered, one arising from the availability of medical services used to prolong the lives of users regardless of their lifestyle, and another arising from adherence to simple laws of nature. This is the Adventist (Biblical) way. The third is the resilience model adhered to by many in Africa where people live long lives despite the ravages of nature, abuse of their own bodies (alcoholism, warrior lifestyle, stress, suicidal tendencies etc in disregard of biblical principles of healthy living). It would appear that God is making from believers a spectacle to the world (I Cor 4:9).
9 For I think that God hath set forth us the apostles last, as it were appointed to death: for we are made
a spectacle unto the world, and to angels, and to men.10 We are fools for Christ's sake, but ye are wise in Christ; we are weak, but ye are strong; ye are honourable, but we are despised.
11 Even unto this present hour we both hunger, and thirst, and are naked, and are buffeted, and have no certain dwellingplace;
12 And labour, working with our own hands: being reviled, we bless; being persecuted, we suffer it:
13
Being defamed, we intreat: we are made as the filth of the world, and are the offscouring of all things unto this day.The chapter is even more interesting considering in context,
I Cor 4
1 Let a man so account of us, as of the ministers of Christ, and stewards of the mysteries of God.
2 Moreover it is required in stewards, that a man be found faithful.
In other words, the health of believers is a manifestation of God's grace that in the things the world despises as foolish and weak (like the plant-based diet advocated by Ellen G. White so often remarked by Prof A.D Hominem on this forum, for example) actually begets something.
