They’re not worshiping her; they’re asking her to put in a good word for them with her Son.
Why don't they ask her living Son instead of a dead woman?
And just why SHOULD she?
If I hire a lawyer; I sure don't need another one to tell him what to do!
Yeah right, could have fooled me.
God is omnipresent, omniscient and does not change. This means he sees everything, knows everything and has determined from the foundation of the world what He will do. He is not moved by anyone because of their status as all mankind is shut up under sin as the Apostle Paul says "All have sinned and fallen short of the Glory of God".
Therefore, Mary is very right to call Him "God my Savior" because He saved her from her sins.
Mary being thoroughly Jewish would not like the statues of her and would say to everyone to worship God alone and that only He can hear and answer the prayers of folks like us.
