The women are instructed to be endlessly patient with their straying husbands and to do everything within their power to keep their marriages intact. Not once were the women (who were sinned against) coached to treat their stubbornly unrepentant husbands like unbelievers or to go to the elders of their Church and ask for church discipline to be applied to the cheaters (1st Timothy 1:20, 1st Corinthians 5:5). Instead the women were encouraged to “make a safety plan” in the event of a “relapse”. None of the safety plans included putting the guy out on the street until he gets his act together and repents permanently (Exodus 20:14, Proverbs 6:32, Matthew 5:27-28, 1st Corinthians 5:9-11).
If addiction were an issue only non-Christians struggled with then there would be little point in me (or any other Christian) addressing the problem. What non-Christians do and don’t do should not be the concern of those inside the Church (1st Corinthians 5:11). It is not our job as Christians to attempt to modify the behavior of those who do not profess faith in Christ. Christians are commanded to pray for non-Christians and share the gospel with them. Period. Forcing a non-believer to act like a believer before they become a believer causes (in my opinion) more spiritual harm than good. Forcing non-Christians to act like Christians simply produces well-behaved heathens with a false sense of security.
