Look at religion and that's what we see, all manner of corruption and violence, plenty of intolerance and "I'm better than you" pride. Look at Jesus and the Bible and I see pure love, humility that generates peace, innocence of nudity, rules that make sense with the basic principal of "do unto others as ye would have them do unto you" Too many people profess to believe in that book and live by it, but don't bother to actually read it and live by it, instead inventing their own rules to live by according to their selfish desires and faulty understanding. If everyone would actually conform their lives to the teaching of that book it would be a wonderful world.
As for skin cancer, it's a product of diet mostly, the sun is only a side issue. I've heard of people eliminating cancers of all sorts just by changing their diet to imitate the original diet gave to man. 100% plant derived and 100% unprocessed and uncooked. As a short term thing blood root salve will kill abnormal cell growth, apply it to the skin cancer, melanoma, mole, wort, or whatever, it dies, pulls loose and falls out, leaving a hole to heal over.
The original perfect lifestyle presented in the Bible, designed by our Creator for our perfect health and happiness, was naturist in style and raw vegan in diet. Nude gardeners getting plenty of sun exposure and eating all the wonderful bounties a tropical paradise garden could offer. As the basic trend of the story goes they lost it due to failing the love and faith test, The Creator invented a rescue plan, and put it in operation. Demonstrating His love in the process as an example for us to follow. And according to the time line laid out in prophecy 2500 years ago we are real close to the end of the process. Yes, every point of those old prophecies in the books of Daniel and revelation have been fulfilled right on time. 7 times in the books of Daniel and Revelation the time period is given that the roman pontiff would rule the world, 1260 years, and it happened right to the very year. 538 AD when the power of the roman empire was handed to the bishop of the roman church, to 1798 AD when the French general took the pope prisoner, effectively eliminating his power. Most professed chrisitians have ignored it all, the few who figured them out in detail get condemned because it's just not very popular to preach that we're on the verge of dooms day and that the "mark of the beast" actually involves the most common christian malpractice of all time which very few are willing to change. But dooms day for this world just means the end of evil and restoration of naturist life in the tropical paradise for those who throw out all their false religions, their loud proclamations of holiness, impressive church ceremonies; and just learn to love others like Jesus did. So that's not a bad thing. The pending end of all evil and reward of all good should be a welcome message.
So why don't all professed christians promote the naturist lifestyle? since it was the original perfect life we had in the beginning, and the perfect life we look forward to at the end. There should be nothing but great benefit to instill all we can of it in the present life. Forgetting to look to the good book for instruction they invent their own rules to live by. They end up calling good evil and evil good. Isaiah said "Woe unto them that call evil good, and good evil; that put darkness for light, and light for darkness; that put bitter for sweet, and sweet for bitter!" And yet religionists have been foremost in doing just that in many areas of life for thousands of years. We need to discard all that religious nonsense, including anti naked foolishness, and get down to the real naked simple truth that true pure religion consists of nothing but love, everything done with love as the motivator. The foundation of the law of God is love, part of it as what we do to show love for our Creator, and the rest being what we do in love to ourselves and those around us. Everything done out of love is a joy to do. If we really love each other we will naturally do it and consider the alternative as unthinkable. "And because iniquity shall abound, the love of many shall wax cold." Matt.24:12
