The Father in Heaven needs his children in the earth to know that they have a Father in Heaven. The only people in the earth who know and acknowledge the Father in Heaven are the people of Islam, the tribe of Ishmael, a son of Abraham, the people of Mohammad the prophet. They are the ones who know that the Lord God Almighty is the Creator of Heaven and of the heavenly realms. They are the ones who know that Jesus Of Nazareth is the Son of the Father in Heaven, not the Son of the Lord God Almighty and that he is a Messiah for all people everywhere of all religions and creeds. They are the ones who know that El Elohim, the Father in Heaven, is a Son of El Shaddai, and that he is the Creator of this present earth only.
The Muslim faith is the only theistic faith that acknowledges the Father in Heaven (Jews acknowledge El Shaddai and Christians acknowledge Jesus) because when Mohammad was alive on the earth, it was El Elohim, the Father in Heaven who appeared to him and gave him the Quran (Koran) as a guide for his people whose lives he was trying to preserve. El Elohim told him that when the time comes for Jesus Of Nazareth to be revealed, they will have the only authoritative proof that Jesus is indeed the Messiah. Most importantly, they also will have the only authoritative proof that the woman of Revelation 12, who gives birth to the children of God's kingdom, is among them.
The Arabic word for kingdom is Mamlaka, and the kingdom is known to encompass all people. When you consider whether or not you wish to begin a tri-faith fellowship or a multi-faith fellowship for the people of God's kingdom, an appropriate name might be The Mamlaka Fellowship, with the town or city as an added means of identification, as for example, The Mamlaka Fellowship of New Orleans, Louisiana, U.S.A. Our God be praised.
The Lord God Almighty El Shaddai
