Unity is raw power. It doesn’t resist being used for good or for evil. Electricity isn’t particular about how you use it either.
Unity empowers people who are like each other with greater strength than they have individually. Unity that includes agreement with an unclean spirit gives that spirit power. Then, the spirit can draw more people into the agreement, and they can keep adding strength until they together give the unclean spirit power to rule over a town or a city or a nation.
The power that is gained when similar people unite is greater than the sum of their strengths. It is multiplied, not just added. It is supernatural, so it affects the realm of the spirit, too.
The greatest power unity can offer, though, is when dissimilar people unite. When enough people of different races unite in an area, they can displace racism’s power if they want to confront it. When people of different religions unite they can overpower truth if they want to confront it.
Of the types of dissimilarities that can unite, the most powerful combination is when believers who have different Spiritual gifts, and different ministries from similar gifts, unite.
When pastors trust prophets, and evangelists trust pastors, and so forth, and bless each others’ perspectives and gifts, they can colonize the earth with the power and culture of heaven. They can overpower darkness if they want to confront it.
