I like the word "Freedom" better and it means the same thing, does it not? Other possible synonyms: Rescue, Release, Liberation, Liberty, even Equality if you think about it. Any other ideas?
"Salvation" is so often used to mean "Conformity", "Similarity", "Right Thinking", and "Law Following", so I may stop using that word.
The American founding fathers built the whole concept of our country and laws on Freedom. It's a functional concept. It guides proper thinking about how to treat others. Certainly not perfect, but it's the right idea. It works in relationships too. Have you ever tried to Save someone in a relationship? That's usually not very healthy and can end badly. Have you ever tried to liberate someone? Give them freedom? That works much better :)
People appreciate it when you encourage them to be themselves instead of pressuring them to be something else.
What does our gospel do? Save people or liberate them?
