Criminals will always be able to have guns or any other weapon of their choice. We are one of the leading countries of the world when it comes to gun trafficking. We feed our kids with a steady diet of violence in the movies, in video games, and most of the action movies are filled with blood, guts and gore. The audience clamors for it, claps and cheers. The bloodier the better. Our society can't seem to get enough. In the movies and video games the victim always comes back to life to fight another day. Our kids don't know fantasy from reality because it looks the same as real life. It's just that in real life the victim doesn't come back to life. And we wonder why there is so much violence. It isn't rocket science. Our minds are like computers: garbage in—garbage out.
Mat_12:34 O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.
Luk_6:45 A good man out of the good treasure of his heart bringeth forth that which is good; and an evil man out of the evil treasure of his heart bringeth forth that which is evil: for of the abundance of the heart his mouth speaketh.
Php 4:8 Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
The solution is to change what we think about. Change what we feed our minds with. Change what matters to us. Change our minds about what is good and what is evil. Change what we see as entertainment. But we are incapable of changing ourselves. We are, after all, frail human beings in need of a savior. There is only one Savior. His name is Jesus. He is the answer to the problem. When we put our trust in Him, He will always be there to help us, even if we lose our children, He will help us through the grief. People who belong to Christ don't commit mass murder. They don't go into schools with guns, or airports, or post offices, or government buildings. Terrorists belong to Satan. He is their master. He is the one they serve and no amount of law or law enforcement can change that. Without God, we all serve Satan by default; we just don't all do it so blatantly.
Give your heart to Jesus. Invite Him into your life and ask Him to be not just your Savior, but your Lord. Your life will not be trouble free, but it will be far more peaceful and you will have someone with you at all times, ready to help. He's only a breath away and He's waiting for you to open your heart's door.
