We are stronger together when we respect each other; trust one another's motives; pray together, and more.
Paul wrote to the Ephesians to encourage them. In the book of Revelation, they were commended for working hard to keep unity; they were patient, endured hardship, and didn't tolerant false teaching. But they became lukewarm.
Paul wrote a letter to encourage them. In Ephesians 1, Paul's prayer is for them to be have inner strength through his Spirit. He prayed for them to develop deep roots so they don't get shaken easily. We need to do the same. To understand how deep God's love is for us. Once we understand, then we are able to put into practice, Ephesians 4:1–6.
Make allowances for each other's faults. We will hurt each other, and make mistakes, instead of fighting. Your kids & spouse & leadership & even yourself.
Make every effort to keep the unity of the Spirit.
