Unity - in practice

Ephesians 4:1-16
Live a life worthy of the calling you have received.
Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace.
There is one body and one Spirit, just as you were called to one hope when you were called; one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all. 
So Christ himself gave the apostles, the prophets, the evangelists, the pastors and teachers,  to equip his people for works of service, so that the body of Christ may be built up  until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ.
Christian unity is a fact. Christian are bound together by a common faith, a common life, common loyalty, common purpose. 
They serve one Master. He is the head, they are the limbs(四肢) of a single body. But they not all identical in temperament, personality or gifts.
The bond must constantly be cemented(凝成) by a loving, forbearing attitude to one another, and by using the different gifts for the common good. We have to grow up together until we are all Christ wants us to be.
Why?
Attitude of a Christian should be 1)humble, 2)gentle, 3)be patient, 4)bearing with one another in 5)love, and 6)keep the unity of the Spirit through the bond of peace. each element is needed and important.
All in one body, one Spirit, one hope, one Lord, one faith, one baptism, one God for he is over all and through all and in all. We are very little one.
How?
Can I use my gift that God gave me to built the body of Christ on the earth? Do my best and follow the way of Jesus Christ.
