It sounds to me as though you view the Christian Lifestyle as a set of "don'ts" and "Thou shalt nots", while the non-Chrisitan lifestyle is the fun way to live. How sad. Christianity is freedom, freedom from bondage to sin, freedom from condemnation for sin. Free to live as God intended people to live. Of course, non-Christians don't see themselves as being in bondage, they see Christians as being the bound-up ones. Another indication of how deceived they are. I don't agree with "forcing" Christian values on those who obviously don't want them, but on the other hand, Christians can't just turn a blind eye to the sin and bondage around us. Jesus came to preach liberation to the prisoners, life to the dead, salvation to the lost, and sight to the blind. Each of those things has both a literal and spiritual application. Non-Christians are "walking dead", "prisoners", "lost", and "blind". They don't see themselves that way, but God does, and it is His opinion which counts. It is our obligation, indeed our duty, to preach the Gospel to the lost, blind, dead prisoners, and as one saint put it, use words if necessary. In my opinion, if Christians would set the proper example, non-Christians would be begging to know how to be a part of such a rich, free, full life.
You're absolutely right on all counts here. But when Christians start advocating prison sentences for private behavior that affects no one else but other consenting non-believing adults, they have crossed the line. Nowhere in the scriptures are Christians told to go pass laws that will result in punishment for non-believers.
