What does the Bible say about peace by Jesus Christ?

In Acts 10:36, it is declared that God sent His message to the children of Israel, preaching peace through Jesus Christ, affirming that He is Lord of all. This peace is essential because, by nature, humanity is at enmity with God. True peace comes not from our own efforts but solely through Jesus Christ, the peacemaker, who reconciles us to God. Ephesians 2 explains that through His blood, we are brought near, and He breaks down the barriers that separate us from God and from one another, establishing a new covenant and peace.
