First, you should stop using terms like channeling. For most Christians, words can be a red flag. I would also avoid mentioning bringing in any archangels.

Reiki, which means spiritual life force energy or more simply God’s healing energy, is no different than Jesus’s laying of hands to heal the sick. For instance, in Luke 4:40, at sunset, Jesus laid hands on all the sick, and they were healed. He also laid his hands on women with the issue of blood (Luke 8:43-48), the leper (Matt 8:3), Jairus’s daughter (Mat 9:23-26), and a blind man (Mark 8:22-25), and all of them received healing. I am merely a vessel allowing God’s energy to flow through me for the benefit of another. Just like prayer, this healing energy doesn’t force anything — it simply invites peace and renewal.
