Listen to this insightful observation of A.W. Tozer:
One hundred pianos all tuned to the same fork are automatically tuned to each other. They are of one accord by being tuned, not to each other, but to another standard to which one must individually bow. So one hundred worshipers meeting together, each one looking to Christ, are in heart nearer to each other than they could possibly be were they to become ‘unity’ conscious and turn their eyes away from God to strive for closer fellowship (The Pursuit of God, p. 90).
Whether it is a political party, a sports team, a family, or a church, unity is found when they have something that they rally around. As you seek to have the same attitude Christ has about me, and I seek to hold the same opinion Christ has about you, we will grow in harmony
