Dusty Idea is the real peace that can be obtained in this world is not about this world. It's not a peace of wars and things. It's the peace that Jesus brought and is available to every man now.
Matthew 10:34 - Do not think that I have come to bring peace to the earth. I have not come to bring peace, but a sword. (ESV)
Christ continues on in chapter 10 of Matthew, following Christ isn't about having peace in this world. He says if we follow him, like he requires to be followed, we'll have enemies in our own households. Side note here, if you're loved by "everyone" including children of the devil(Acts 13:10), you're probably not doing something right. Christ says you will be hated for his names sake(John 15:19). If you're not being hated on by someone, you better check yourself out. You've probably compromised with the devil on something, and possibly only you know what it is.
John 14:27 - Peace I leave with you; my peace I give to you. Not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid. (ESV)
The peace that Christ brought isn't a peace like between governments. Christ brought the ability for us to have peace with God. To have our sins forgiven so we can be reconciled back to God. The peace that Christ left us with is peace with God almighty.
John 16:33 - I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world." (ESV)
Colossians 3:15 - And let the peace of Christ rule in your hearts, to which indeed you were called in one body. And be thankful. (ESV)
Ephesians 2:13-17 -13But now in Christ Jesus you who once were far off have been brought near by the blood of Christ. 14For he himself is our peace, who has made us both one and has broken down in his flesh the dividing wall of hostility 15by abolishing the law of commandments expressed in ordinances, that he might create in himself one new man in place of the two, so making peace, 16and might reconcile us both to God in one body through the cross, thereby killing the hostility. 17And he came and preached peace to you who were far off and peace to those who were near. (ESV)
We see in verse 14 above he is our peace, he is the Prince of Peace. He took the old law out of the way so Jew and Gentile could become one people in Christ and could be reconciled with God. Why did he take the old law out of the way? Simple, because it was in the way of everyone having salvation.
What was the price of peace? It took the pure lamb of God to be sacrificed on the cross. Hebrews 9:22 says without the shedding of blood there is no remission of sins. No one can be reconciled or get into a friendly relationship with God without the blood of Jesus. Some people say that the Church isn't important. When you say that you're saying that the blood of Jesus isn't important, because that's what it took to purchase the Church.
Then we have the people of peace, Matthew 5:9, Blessed are the peacemakers for they shall be called the children of God. All the children of God are peacemakers. If you are a member of Christ's church and are actively seeking to save that which is lost, you are a peacemaker when you strive to help other people have peace with God.
