In Matthew 4, trusting in God to protect you in every day life situation (That God has put you in), is in no way related to forcing a situation yourself in order to get God to protect you. In other words, there is a big difference between throwing yourself in a pool of sharks with chum in it (And testing God on whether He is going to protect you) versus say trusting in God to protect you when you swim in the ocean (Either at the beach and or because you were forced to do so because your boat broke down). For do you wear shark body armor every time you swim in the ocean? How about if you just dip yourself in the water at waist length for a few minutes? Should I call someone to go get the shark body armor or some kind of iron man suit if you do decide to take a dip in the ocean at waste length? Where is your faith? Do you actually believe God needs you to carry a gun or a sword?
If you were to read the New Tesament at any length on the topic of persecution, you would realize that the apostles did not fight back, but they endured suffering and hardships in order to preach the gospel. Just as Christ suffered we are to emulate Christ. We are to conform to His image. He set the example. Are we not to follow his actions? How about the examples of the apostles? Where did they ever attack others physically with their fists and or with a sword? Did Steven try to pick up the stones and throw them back at his accusers? No, no. Most certainly not. He prayed for them in the hope that God would not hold their wrongful actions against them. Jesus did the same thing. He prayed to the Father to forgive those who were crucifying Him, for they did not know what they were doing. Yet, your message is contrary to that, though.
For Jesus came not to judge, but to save. We are under the age of grace and not the age of the Law of Moses.
Yes, Jesus will return with His saints and destroy those evil nations that have refused to repent.
But for now, God has commanded us to turn the other cheek and to do good towards our enemies. Killing them is not doing them good. In other words, if God tells you to stop. You stop. If God tells you to go, you go.
There are non lethal ways to stop violence. It's called peace making. Have you ever thought of rebuking them in the name of Jesus Christ to stop and tell them that Jesus loves them? Did you ever think of quoting Scripture? Remember when Peter could have walked on water? Why couldn't have walked on water? It was because he lacked faith. See, God doesn't need you to punch people. He could give your enemy a heart attack or make them to feel great terror at your words (If you simply believe). For the weapons of our warefare are not the weapons of this world. In Ephesians 6, it tells us to put on the whole amor of God.. This is not talking about physical body armor and a sword. This is talking about spiritual armor and the Word of God.
Yes, Jesus did not mean a literal sword. God is not going to tell you to buy a physical sword and then later rebuke you for taking up your sword that He told you to just buy. That would be confusion; And God is not the author of confusion. Also, if you were to look at the OT reference, an eye for an eye and a tooth for a tooth, etc. This was clearly in reference to executing Judgment upon another physically. In other words, if someone takes your eye, you take their eye, etc. See the OT reference. When you understand that OT passage, you will understand the context of what Jesus was talking about. Turn the other cheek is in reference to that.
