i would say yes logically, our body is our temple and if we ourselves may not violate it- then we shouldnt let anyone else violate it- but can we find scripture beyond the times of moses to support this? the new testament?
i think best bet is still- being married having a duty to stay alive for your wife and family which naturally needs you
You're right to seek clarity from Scripture, especially from the New Testament, and it’s wise to think beyond just logic and into what God’s Word says about life, responsibility, and righteousness. While the New Testament doesn’t give us a direct command saying “defend yourself,” it absolutely affirms the value of human life and our responsibility to care for others—including ourselves and our families.
In Luke 22:36, Jesus told His disciples,
“Let the one who has no sword sell his cloak and buy one.” This wasn't a call to violence, but an acknowledgment that danger exists and being prepared is not inherently unrighteous. When Peter later used a sword to strike in defense of Jesus, Christ told him to put it away—not because self-defense is always wrong, but because Jesus was willingly laying down His life to fulfill the Father's will. That was a unique situation tied to His mission to die for sinners.
Paul, too, appealed to Roman protection when he was in danger (Acts 22:25–29), showing he did not simply accept harm when it could be lawfully avoided. And 1 Timothy 5:8 tells us,
“But if anyone does not provide for his relatives, and especially for members of his household, he has denied the faith and is worse than an unbeliever.” Providing doesn’t just mean food and shelter—it includes protection. If we love our families, we will seek to guard their lives as well as our own.
So, self-defense—when it’s rooted in love, not hatred or revenge—is consistent with Scripture. It’s not about returning evil for evil (Romans 12:17), but about valuing life as God does. The key is the heart: we are called to live peaceably with all, as much as it depends on us (Romans 12:18), but protecting life, especially those entrusted to us, can be a righteous expression of that love.
