When we pray we are communicating with GOD. We aren’t just talking to the roof or stars. We are communicating with GOD via Jesus Who is seated at HIS Right Hand. Angels ascend and descend upon Us as we pray.
We’re also communicating with God via the Holy Spirit within us who is of course also God
If you remain in Me, and My words remain in you, ask whatever you wish, and it will be done for you. 8My Father is glorified by this, that you bear much fruit, and so [g]prove to be My disciples. JOHN15
