What exactly are we treating and/or trying to prevent?

I'm not sure the correct way to say this exactly, but I'm going to do my best. It may seem a little radical, or crazy, to people in the medical professions, but this is what I'm thinking about. 


There are so many articles and studies and statistics that point to childhood trauma, addictions, sexual promiscuity, and many other problems of our time which have a huge impact on the prevalence, spread, and/or treatment of many diseases. For example:


Sexual promiscuity -> STDs, AIDS, Teen pregnancy, single mothers
Divorce, childhood trauma, addictions; & Abuse - Verbal, physical, sexual
-> chronic illness, many stress-related or stress-provoked diseases, mental illness, depression, earlier death


I could go on and on. But so many of our nation's (and the world's) health and psychological problems, and the problems that those problems lead to, can be attributed to unbiblical ways of living and ideals that go against God's design. 


What if, instead of teaching safe sex, 'equitable' divorce, and violence, we taught about Christ and his saving and redeeming power, the biblical model for marriage (sex) and parenting, how to love one another with gentleness and yet with strength, how to stand up for one another instead of put each other down, and ways to cope with stressful situations, anxieties, and fears from a biblical perspective? What if by promoting healthy families, biblical men and women loving and committed to each other and working together to raise children, we were able to prevent so many of these problems today? How about championing Christ's power over any addiction or disease? What if the problems of our society do not just lie in systems and poverty and disease, but in the fact that we are not in a right relationship with God and living according to his principles? What if these things could eliminate divorce, sexual promiscuity, STDs, teen pregnancy and single parents, addictions, and abuse somewhat eliminating poverty, chronic disease, and depression? How much pain and suffering would we preventing? How many programs and projects would we be able to eliminate, thereby saving resources and time to devote to other aspects and others who are more in need?  What if God's way is better, because that is the way it was supposed to be, and actually has a meaningful impact on how much disease and suffering there is in the world? What would happen if we focused on God's ways instead of the world's ways? 


I hope this made some sense - I'm sure I'll post more about it in the future to clarify things. It's basically just a bunch of questions I have about the way medicine, specifically preventative and reactive medicine is performed.
