Guns are not the problem. They are merely the tool used to carry out the evil in men's hearts. If guns are gone another instrument will be used or devised. The problem is a world devoid of God and a people bent on evil. Only the Truth can set us free from our bondage to Satan's wiles. As long as God continues to be left out of the equation peace will never be the end result.
Because we live in this sinful world we must have an awareness of evil. There are those Christians who claim not to believe in the devil. (As Pastor Minter said, "Not believing in him does not keep him from acting.) It is my belief that a Christian who does not believe in Satan will have more struggles with faith as they rob themselves of the scriptural reason behind the pain, evil, and suffering in this world.
"Be
well balanced (temperate, sober of mind), be vigilant and cautious at
all times; for that enemy of yours, the devil, roams around like a lion roaring
[[f]in fierce hunger], seeking someone to seize
upon and devour. Withstand him;
be firm in faith [against his onset—rooted, established, strong, immovable, and
determined], knowing that the same ([g]identical) sufferings are appointed to your
brotherhood (the whole body of Christians) throughout the world. And after you have suffered a little while, the God of all
grace [Who imparts all blessing and favor], Who has called you to His [own]
eternal glory in Christ Jesus, will Himself complete and make you
what you ought to be, establish and ground you securely, and strengthen,
and settle you." 1 Peter 5:8-10
"I
have told you these things, so that in Me you may have [perfect] peace and
confidence. In the world you have tribulation and trials and
distress and frustration; but be of good cheer [take courage; be
confident, certain, undaunted]! For I have overcome the world. [I have deprived
it of power to harm you and have conquered it for you.]" John 16:33
