Regarding a Christian’s responsibility, or responsibility of every good person for that matter, we must live rightly personally.
We must live justly, do justice, walk in mercy, show kindness, and keep sight of the fact that we are not the center of the universe; we are not the judge; we must remain humble.
That seems to me to require that I NOT try to impose what is right on anyone else. Just because certain things are obviously good for society, it does not follow that I, or the government, or any other powerful agent should impose on society.
It is all about relationships. Jesus told us to follow Him. Jesus told us to make disciples. It must be about our daily, personal walk and individual relationships.
It’s not about the President. It is not about SCOTUS. It is not about laws. It is about individuals choosing to do what is right and choosing to be involved in the lives of those around them. Involved relationally, not nosily. Involved lovingly, and considerately, not with an eye to gain an edge or leverage. Understanding, not meddling.
