The power which is released through unity is so great that literally nothing is impossible to those who will unite themselves that means agree on the same purpose, have the same goals and same motives.
There is no division in the Godhead, that is between the Father, the Son, and the Holy Spirit. They are perfectly one, perfectly in agreement, in perfect unity. Now they have different roles and responsibilities, but they have one purpose. They are united in purpose and goals.
We will never see the total, awesome power of the Holy Spirit in your life, in your home, in your church, in this society, in this nation, until there is a oneness of Spirit, among the church. Those in the local church must be united in vision and purpose. Putting away all differences and all desires for supremacy If there is no unity of purpose and vision, there will be no presence of Christ and thus no power for witnessing and evangelism.
