“Channeling” is a term often used by spiritists and others to describe the way in which spirits from the spirit world can be brought into action in this material world through human channels.
Christians naturally (I use the word deliberately) shy away from such things.
However a Spirit filled Christian is a temple of the Holy Spirit according to Scripture (I Corinthians 6:19) and therefore should actively be channeling Him into this world. Jesus was the ultimate example of this. He is the spiritual Word made flesh (John 1:14), channeling God into the world through His flesh and we also ought to be the same.
And if you want to extend the influence of the Holy Spirit beyond your own physical sphere you can pray.
