For Baha’is… Prayers can go directly to God as well as through intercessory channels…
Whilst ye consort with him, the Concourse on high will be looking upon you, will be interceding for you, will be extolling your names and glorifying your action.
(Baha'u'llah, Gleanings from the Writings of Baha'u'llah, p. 314)
The wealth of the other world is nearness to God. Consequently it is certain that those who are near the Divine Court are allowed to intercede, and this intercession is approved by God. But intercession in the other world is not like intercession in this world: it is another thing, another reality, which cannot be expressed in words.
(Abdu'l-Baha, Baha'i World Faith - Abdu'l-Baha Section, p. 329)
Praying directly to God:
Turn thy face sincerely toward God; be severed from all save God; be ablaze with the fire of the love of God; be purified and sanctified, and beseech and supplicate unto God. Verily, he responds unto those who invoke him, is near unto those who pray unto him. And he is thy companion in every loneliness, and befriends every exile.
'Abdu’l-Bahá from a Tablet to American believer; translated by Dr 'Alí-Qulí Khán, Boston, February, 1908.
