Godly Discord or Bogus Unity?

Why would God sow seeds of discord when he has declared that it is one of the 7 things that He really hates? When two opposing sides are at war with each other they both strive to not only create unity in their own camp, but to sow seeds of discord and confusion in the camp of the enemy.  We see this strategy in spiritual warfare: the continuous battle between God and satan.  The devil is not alone in employing the use of discord.  God himself has made use of this tactic.

An obvious example of this would be the confusion of tongues at the Towel of Babel.  Genesis 11 describes how these people tried to increase their unity; which would make them less vulnerable and less dependent on God.  Satan was the instigator of this scheme, but to stop him God turned their unity into confusion.  In the words God spoke at that time, I think that it is remarkable to see the strategic value God attaches to unity.  In verse 6, "The Lord said, Behold the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do."  He says, ..."let us go down, and there confound their language, that they may not understand one another's speech."  We also find many other biblical instances of God bringing confusion among those who tried to frustrate His plans.  His strategy has been to curtail His adversary's strength by sowing seeds of discord among people who are under satan's power.

Along with this tactic of confusion, we also see in the Bible how God seeks to unite His own people.  In contrast to the incident at Babel, when people no longer understood each other and were dispersed in all directions, Pentecost (in Acts 2) was a day when people from many nations came closer to each other because the Holy Spirit enabled the Apostles to speak to them in their own language. In the New Testament, our unity as Christians is strongly linked to the Holy Spirit.  In Ephesians 4:3, the Apostle Paul says that we must keep the unity of the Spirit, and reach unity in the faith (verse 13).  Our unity in the Spirit is a fact to be kept while our unity in the Faith is a calling to be reached.  If our unity in the Spirit is indeed a fact and He, Holy Spirit, works for our unity, why is there so much discord among believers especially in regard to our views about the Holy Spirit? There are plenty of people who are working together in unity, but they are not working together in the unity concerning the things of God.  They are working together in unity to accomplish the things of satan.
