Prayer?
Here is the cut & paste from acts:
And when the day of Pentecost was fully come, they were all with one accord in one place. And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Spirit, and began to speak with other languages, as the Spirit gave them utterance. And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven. Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language.
Communication between people through thought is simple if you can tune the two individuals to the same frequency. It’s like using a wireless microphone with a transmitter and a receiver. They must be synchronized or they will not work.
This is why couples in a relationship begin to tune into each other’s thoughts. Emotions increase the volume of the transmission.
Thus when Jesus gave us the two most important commandments in response to the Pharisees question about the commandments, Jesus was telling us to focus on tuning into the frequency of God by Loving Him (staying focused upon) with your mind, body & soul.
In the second commandments He was telling us to let go of all the anchors that are keeping us focused on the lower frequencies and blocking us from tuning into God. It really is that simple.
When we learn to do this it makes our religion experiential rather than just theoretical.
