So many people have conflicts with others. Husbands and wives have conflicts, kids and parents hurt and offend each other, and people in the work place are often bickering. Jesus prayed that we would be as unified as He and God the Father were. The Bible is full of guidelines on how to be at peace with everyone in your life. The most important principle is work very hard at it, do the hard things that need to be done to be at peace with those in your life.
Romans 14:19 So then we pursue the things which make for peace and the building up of one another.
A second principle is to continually practice deference. Deference is a very important character trait that most people don’t have, at least not much. Deference is putting other people and their needs ahead of our own needs. Deference is guarding our mouth so as not to say things that offend other people. Deference is limiting our freedom so as not to be a reason that those around us are hurt. There are certain character traits that especially please God, and deference is right at the top of the list. It takes a lot of work to successfully practice deference, it takes a lot of self sacrifice, a lot of giving, a lot of self-control and a lot of humility to be the one who initiates reconciliation.
