A "culture war", if that means legal or political action, is NOT WHAT JESUS TOLD THE CHURCH TO DO.
You're dead on. Certainly on can participate in politics, but, ultimately what will change the hearts and minds of people is Christ, and Christ alone.
True. But don't reduce what Christ is doing through His people. He's doing more than just preach the gospel thru them.
We need to get back to the purpose & reason Christ came. What does John say that reason was in 1 John 3:9? "The reason the Son of God appeared was to destroy the devil's work."
What was the devil's work? Sin, as manifested in countless ways. But let me define some of those ways: Abortion, homosexuality, lust, pornography, trafficking of people, gambling at the expense of the poor, etc. etc. etc. Are not acts of murder, abortion, etc. among the kingpins of Satan that Jesus came to destroy? (And are we only to fast-forward the halting of carnage to some rapturous moment?)
Now, true, Christ alone acts, but He is embodied now in a people (John 17:23; Acts 9:5; Eph. 2:19-22). He chooses to act both directly (Acts 9) and indirectly through His Body. Was all of the devilish destruction accomplished at the cross? Not according to John (John 14:12) or Paul (Col. 1:24,29).
Hey, if there's any reason the two books of the Corinthians exist in Scripture, it's to let us know that while a major transformation already took place in the lives of these folks (1 Cor. 6:9-11; 2 Cor. 5:17), they were far from injecting that inward transformation into their relationships (tolerating a man sleeping with his father's wife--1 Cor. 5:1).
Do you mean to say that "presto, upon conversion, all Christian male teens & young adults are thereby not bothered by easy access to porn since we've changed their hearts & minds & therefore why bother changing porn laws?"
"Fighting the culture war", to me, means being politically involved and taking action to clean up our culture wherever possible.
