Jesus, the apostles, the earliest followers of Jesus (until the 4th century) and a minority of Christians down through the centuries defended themselves without using the weapons of the world.
So you think Jesus committed sin when He said to get a sword (deadly weapon)?
Luke 22:36
Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one.
Luke 22:36 is a verse where Jesus instructs His disciples to take provisions for their journey, emphasizing that if they do not have a sword, they should sell their cloak to buy one. This reflects a shift in their circumstances, indicating the need for preparedness in facing upcoming challenges including the need for self defense.

We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.
John 14:30
the prince of this world cometh, and hath nothing in me.
