"If it is possible…..live peaceably with all men"

I love the way Scripture puts this.

Romans 12:18(NKJV)

If it is possible, as much as depends on you, live peaceably with all men. 

What I believe this is telling us is that sometimes it is out of our control whether we live peaceably with all men or not.  There are some men who it simply will not be possible to live peaceably with; because of their actions. 

If we have done all that we can to live peaceably with others then we have fulfilled our obligation.  It is not a sin to defend ourselves at this point.

After all, there is a reason that Jesus told us to arm up!

Luke 22:35-37(NKJV)

And He said to them, “When I sent you without money bag, knapsack, and sandals, did you lack anything?” So they said, “Nothing.”

Then He said to them, “But now, he who has a money bag, let him take it, and likewise a knapsack; and he who has no sword, let him sell his garment and buy one. 

For I say to you that this which is written must still be accomplished in Me: ‘And He was numbered with the transgressors.’  For the things concerning Me have an end.”
