David was such a GREAT example of being "free" in God and allowing the Holy Spirit to move a person "free" and allowing the Holy Spirit to be FREE in and through them.
Now, imagine a church FULL of people free like David. Imagine a whole church FULL of people free in the Holy Spirit and dancing and worshiping as they are led in the Spirit?
John 4:23 But the hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for the Father is seeking such to worship Him. 24 God is Spirit, and those who worship Him must worship in spirit and truth.”
Many other Christians who are bound by their church rules or "order" would look in the door and react the EXACT same way that Davids wife did... so many DO react this way today and then they ask why God doesn't manifest in their church. It's because their rules and order has the Holy Spirit ordered to sit down and be quiet like everyone else in the church.
A church of just a few friends? Do you mean a fellowship gathering? My answer would be no as there are 9 gifts and only a small portion will be used by God to empower a "church". Just a few friends who are fellowshipping separate from their church or from the churches that are provided and stood up by God in an area where such a few have decided that they would rather do their studies and fellowshipping in the name of Christ away from church... no, I don't see God manifesting "all" the gifts. He's not gonna create a "super" group who only minister to themselves away from church where people are free to walk in from off the street and receive a message from Christ, get prayed over or be ministered to from a church. Such a group that has completely separated themselves from church or the Body of Christ, cannot be used to reach out to the world (the lost) and I don't see God manifesting at all as they only minster to themselves.
Did the Apostles hole up somewhere and just minister to themselves? They had moments, and personal ministering where they did... thus the purpose of home Bible Studies, home fellowship.. but not to REPLACE the purpose of a church. They stood up churches and this continues today... not for people to "hide" themselves away from but to draw people to God, be "fed", by God, be ministered to, by God, to be healed, by God, to dance, to God, to worship, to God... we can all do this alone... but NOT separated from the Body of Christ and go it completely alone.
Church is led by a man that God has gifted to be a Preacher, a shepherd that Jesus will use to lead a flock... Bible studies, fellowshipping, home studies etc.. are led by "teachers". Those led to "teach".... Preachers are used by Jesus to give HIS message of conviction, healing, and when needed of learning. These groups reserved for small group study... to learn the Bible, to pray, to minister but the "message" that Jesus would bring to the Body of Christ is through those that are anointed to preach the Gospel, not simply teach the Gospel.
If a person who knows they are "anointed" by Jesus to be a preacher... they would also find themselves provided for by God... a building to be used as a church, people walking in off the street who are in need of a shepherd, let's say it.... money to pay the bills and provide for him and his family, people who will help him (ministry leaders, people skilled in administrative management/logistics to help run the church, a PURPOSE and once all these elements (and this example is lacking in much) are in place and God has a "church" He can utilize to GLORIFY Himself through... then He will begin to move in power.
This "building" that such a preacher finds themselves provided... as God sends him more and more flock, they will be led to a bigger building or provision for the expanding congregation will be made available to by God.
I don't see this happening with a group that has decided to separate themselves from all this.
Why would anyone want to hole themselves up and be separate from the rest of the Body of Christ and think that they are conducting "church"?
