God HIMSELF implies certain people's prayers ARE more efficacious than others.
See Jeremiah 15:1.
And yes, just to tweak your nose, it is in Jeremiah (Chapter 7 or so) where the "Queen of Heaven" is mentioned.
Didn't Jeremiah live long before Mary?
Cheers!
You’ve used the phrase “to tweak your nose” twice with me. What does that mean? Are you trying to be cute in your rejection of Christ the Savior, who reigns far above Mary my equal before God?
