This is a question that many of us disagree on, in general. I am not bothered by those who disagree with me, as long as they are living based on what they believe the Word of God to teach on this matter.
My view is that it is clear from Luke 22:38 (and other passages) that Jesus did not forbid the carrying of a sword (weapon) to the Christian:
And they said, Lord, behold, here are two swords. And he said unto them, It is enough.
After Jesus told the eleven disciples that the two swords were enough, they carried these two swords to the Garden of Gethsemane where Peter used one to cut of the servant's ear. After this was done, Jesus told Peter in John 18:11b:
Put up thy sword into the sheath: the cup which my Father hath given me, shall I not drink it?
Of course, Jesus' focus was on being obedient to the Father, but He also told Peter to put the sword into the sheath; He did not tell Peter to cast it away. The assumption would be that the disciple carrying the other sword never drew his.
For the sake of brevity, here are some other short Bible verses on the subject:
Ex 15:3 The LORD is a man of war: the LORD is his name.
Num 32:6b Shall your brethren go to war, and shall ye sit here?
Rom 13:4b he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil.
My point is that, as Jesus taught, we are not to live by the physical sword, but rather the spiritual one: the Gospel. The gospel was not intended to cut off the hearer's ear, but rather to stab the heart (spiritually). There is not some great biblical teaching that we are to take up a sword, neither is there one to cast it away; but rather a practical lesson that there is, as Solomon put it:
Qoh 3:3a A time to kill, and a time to heal
I will protect myself, my family, and my country, as long as I can best discern that it is the will of God. If I see that God guides me to be taken captive and give my testimony before rulers, then so be it; but there are many of Jesus' (and other biblical) teachings that make self defense practical, as well as passivity:
Prov 17:12 Let a bear robbed of her whelps meet a man, rather than a fool in his folly.
Matt 24:43 But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up.
Luke 22:36b he that hath no sword, let him sell his garment, and buy one.
History has shown that the gospel has flourished under the sword of enemies (first century Romans, modern-day Africans), as well as under the defense of the sword (Wesley, Spurgeon). The sword is what it is: a tool. The evil lies in the man who uses it to do evil. But as said earlier, the one who bears the sword to bring justice to those who do evil (quoting the inspired words of the Apostle Paul from Romans 13:4) is:
"the minister of God to thee for good."
