What is the Church?
the Body of Christ
Church is more than just a building that houses people of Christian faith... it is the people that make up the church... not the building.
Our Lord Jesus is the head of the church and we as believers are the body.
22 And hath put all things under his feet, and gave him to be the head over all things to the church, 23 Which is his body, the fulness of him that filleth all in all. Ephesians 1:22-23
Christ sent his disciples into the world to be witnesses of Him and draw humanity to himself... We are all promised a place with our Lord if we obey the gospel and endure to the end when Jesus will redeem his church for himself.
If you are not part of a locally assembly... find one to join... As long as it teaches salvation comes through repentance, baptism in Jesus name, and infilling of the Holy Spirit with the evidence of speaking in tongues and also that Christ is Lord... then let no other doctrine cause division
