Reasons Miriam/Mary should NOT be “prayed to” and cannot be our intercessor, mediator, advocate, helper or benefactress:
 She was not YHWH’s Messiah.
 She was not “the Mother of God” (GOD doesn’t have a “mother”).
 She, mother of YHWH’s divine Messiah, is a mere human.
 She’s dead!
 Nowhere in the Bible does it say she went straight to heaven.
 Not once are we told that she has been resurrected or "sits at the right hand of God" (as in the case of Yeshua - Colossians 3:1).
 She was simply the righteous vessel YHWH chose to give birth to His Son.
 Even Mary herself understood SHE was not to be praised or worshipped (Luke 1:45-50).
Since Miriam was still alive when Yeshua died on the stake (John 19:26-27), it means she wasn’t “resurrected” or taken up bodily in any shape or form. We know of no other "resurrection" since the day Yeshua died when there was a great earthquake, and some dead believers were "resurrected" (Matthew 27:50-53).
Therefore, Mary must wait until Yeshua's Second Coming when many believers will be "caught up in the air to meet him" (1 Corinthians 6:14; 1 Thessalonians 4:13-17). (The final "catching up" of mankind will happen at the end of Yeshua's thousand year reign when we will ALL stand before YHWH on Judgment Day (Revelation 20:11-15).)
While being chosen to give birth to the Messiah was a huge honor, this did NOT make Mary "the Mother of God" (can GOD have a mother?) and she is NOT someone to idolize or to "pray to." Yeshua was our Messiah, a human with a divine Nature – and that Nature was divine because he was YHWH's Son!
Yeshua Himself taught, "This, then, is how you should pray: 'Our Father in heaven....'" (Matthew 6:9). Yeshua intercedes on our behalf to the Father (Hebrews 7:25). The Bible teaches that we have access to the Father only through Yeshua (John 14:6; Ephesians 2:18; 1 Timothy 2:5). Therefore, we should be praying to the Father, in Yeshua's Name (John 14:13-14).
