Can this be justified by Scripture, or is this just your personal beliefs apart from the Bible?
The underlying argument for gun control seems to be that the availability of guns causes crime. By extension, the availability of any weapon would have to be viewed as a cause of crime. What does the Bible say about such a view?
Perhaps we should start at the beginning, or at least very close to the beginning -- in Genesis 4. In this chapter we read about the first murder. Cain had offered an unacceptable sacrifice, and Cain was upset that God insisted that he do the right thing. In other words, Cain was peeved that he could not do his own thing.
Cain decided to kill his brother rather than get right with God. There were no guns available, although there may well have been a knife. Whether it was a knife or a rock, the Bible does not say. The point is, the evil in Cain's heart was the cause of the murder, not the availability of the murder weapon.
God's response was not to ban rocks or knives, or whatever, but to banish the murderer. Later (see Genesis 9:5-6) God instituted capital punishment, but said not a word about banning weapons.
Exodus 22:2-3 tells us "If the thief is found breaking in, and he is struck so that he dies, there shall be no guilt for his bloodshed. If the sun has risen on him, there shall be guilt for his bloodshed. He should make full restitution; if he has nothing, then he shall be sold for his theft."
Another question asked by Christians is "Doesn't having a gun imply a lack of trust that God will take care of us?"
Answer: No That is why we have weapons and firearms in our possession.
"What are you afriad of by owning a weapon?
