Ecclesiastes 3:
To everything there is a season,
A time for every purpose under heaven . . .
A time to kill,
And a time to heal . . .
A time to love,
And a time to hate;
A time of war,
And a time of peace.
Luke 22:
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.”
So they said, “Lord, look, here are two swords.” And He said to them, “It is enough.”
Not being a cafeteria Christian, I take the entire Bible as guidance. There is a significant element of forgiveness and turning the other cheek, but there is also more than enough approval for using weapons when necessary. The Bible is not for sissies or for wimps.
