You cannot expect any prayer addressed to the virgin Mary to be heard. She is a human being like you and me & not deity. Almighty God is no respecter of persons. (Acts 10:34) He will not listen to Mary any more than He would listen to Naomi or Boaz, but He is open to the prayers of all His people.
Almighty God says in Jeremiah 33:3, “Call unto me and I will answer you, and show you great and mighty things, which you know not.” Any of Almighty God’s people can call to Him and expect to be heard.
He says in Matthew 7:7, “Ask and it shall be given you.” The Almighty invites us to ask Him. He does not say for us to employ mother Mary in our praying, if we want to receive from Him.
First Timothy 2:5, “For there is one God, and one mediator between God and men, the man Christ Jesus.” Christ is the ONLY mediator. Yahshua Jesus would have told us to inquire through His mother Mary, if that had been necessary, but He does not.
I challenge anyone to show in the Holy Bible, where Almighty YHVH directs Christians to pray to Mary. It is a tradition that was started long long ago by men, without any Holy Bible basis. It is not a requirement of Almighty God, and quite frankly is an improper way to the Father. No man goes to the Father except through His only Son. (John 14:6)
Yahshua Jesus’ disciples asked Him to teach them how to pray. He teaches them to open their prayer by saying, “Our Father which are in heaven.” (Matthew 6:9) You see, Christ taught them to talk directly to the Father. That goes for you too my friend. Read Matthew 6:9 for yourself. It is what we call the LORD’s prayer. The way to pray is to start talking to the Father up in heaven.
The heavenly Father wants you to talk to Him. You don’t need a priest or mother Mary to have an audience with the Almighty, for He teaches us in His word, that He wants us to ask Him, to seek after Him, to knock on His door. We do not need to send anyone in our place; in fact, our relationship with Him is first person singular.
Notice in John 16:23, that really our prayers are to be directed to the Father and we can ask in Yahshua Jesus’ name. If you want to get your prayers answered, then come with a sincere heart of faith directly to the Father and He will hear you.
