Disunity is destructive in homes, churches, work places, team sports, government, everywhere. God calls us to be at peace with all men as far as it depends upon us. Pursue peace with all men.
Few homes have unity. The husband and wife are constantly arguing with each other. The children are fighting, hence the term sibling rivalry. A house divided falls. Stop arguing with your spouse. Train your children to not argue. Teach them to love each other.
Few churches have unity. There are so many arguments about doctrinal issues. God calls us to love others not argue about doctrinal issues. No one knows God perfectly. We aren’t God and don’t have the mind of God. I just know criticizing and tearing each other apart is far from the heart of God.
Few work places have unity. As a believer, do your work heartily as to the Lord with joy in your heart. Be a servant to your fellow workers and let the love of Jesus shine through you brightly. One person living like Jesus can permeate a work place and change it. Pray for your fellow workers.
Few sport teams have unity. Teach your children to listen and obey their coaches. Teach them to have good attitudes even when they are not being fairly treated. Teach them to be kind and loving to their teammates. God is pleased with this kind of behavior.
I am not sure what the solution to government is except that we are called to pray for our leaders and speak evil of no man. If all Christians took this command seriously, our government might be in a much better place.
So seek peace and pursue it. Don’t let disunity destroy your marriage, your family, or your church.
Walk worthy of the vocation wherewith you are called, with all lowliness and meekness, with long-suffering, forbearing one another in love; endeavoring to keep the unity of the Spirit in the bond of peace.
