The devil gets into Christian churches with his deceptions because the Truth isn't being taught. So, consequently, those people are living in a lie because they're being deceived. When the Truth is taught, the devil has to go ... he cannot stay around where the Truth is.
Someone asked a question: "I've had opportunities to lay my hands on people and pray that they receive the baptism in the Holy Spirit. So, in the praying of this, does Jesus release the Baptism from Heaven?"
No ... He doesn't have to release it from Heaven because He is in us and goes from us to the person being prayed for. He doesn't have to go clear back to Heaven to bring it down. The Holy Spirit is everywhere.
