Galatians 5:22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness...
Throughout the Bible there are many different references to peace with varying meaning. You have peaceful relationship with God because of Jesus' death on the cross. Because of the Holy Spirit, you may have peace of mind in situations where you might otherwise feel stress or anxiety. While God manifests peace in your life in both of those ways, in this verse, Paul is using peace to describe peace and harmony between individuals.
When it comes to relationships, it is easy to have peace with the people you spend most of your time with. That's why you like them most likely, because it is easy for you to be around them. You probably see eye to eye when it comes to topics, you are in similar stages of life, and you might have a great history together. While the Holy Spirit produces peace in your life in those easy relationships, it is also easy to brush aside the relationships with people in your life who you don't get along, don't see eye to eye with, and maybe have a rough history with. The fruit of peace in your life shouldn't be bound to particular people, but should instead flow into all relationships in your life. Peace should be carried with you to all people, despite place or circumstance.
what does peace look like for you?
Peace in relationships with others might look differently than what you would expect. It doesn't mean you let people run over you. It doesn't mean you don't talk about difficult things with people. To have peace in your interactions with other people means that you value them as a son or daughter of Christ above all else. It might mean that you choose to show people grace and forgiveness when it comes to how they have wronged you in the past. It might mean that you talk to the person or group of people that you disagree with, or are very different than you, and be receptive to what they have to say. Peace from the Holy Spirit allows you to be in relationship with people who you would otherwise never be able to.
To end, think about people in your life who you think would benefit from you bringing peace with you next time you interact with them. It might be a roommate, friend, or family member. Ask God to fill you with humility and peace. Ask Him to give you ideas of what it looks like for you to carry the peace of Christ with you.
