Unity is strength and Unity bring blessings. 

Psalms 133:1-3 Behold, how good and how pleasant it is For brethren to dwell together in unity! It is like the precious oil upon the head, Running down on the beard, The beard of Aaron, Running down on the edge of his garments. It is like the dew of Hermon, Descending upon the mountains of Zion; For there the Lord commanded the blessing—Life forevermore.

Matthew 18:19-20  “Again I say to you that if two of you agree on earth concerning anything that they ask, it will be done for them by My Father in heaven, For where two or three are gathered together in My name, I am there in the midst of them.”

Acts 2:1-4 When the Day of Pentecost had fully come, they were all with one accord in one place. And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. Then there appeared to them divided tongues, as of fire, and one sat upon each of them.  And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance.
