In that day you will ask in my name, and I do not say to you that I will ask the Father on your behalf; for the Father himself loves you, because you have loved me and have believed that I came from God.
John 16:26-27

If even the intercession of the Son of God himself can't make the Father love us any more, what power do you think dead people have? Solomon said "the dead know nothing", and David said that the dead neither remember nor praise God. Moses said that anyone who tries to talk to the dead are an abomination to God. Praying to dead saints, even Mary, can't help you and will definitely hurt you.

You can pray directly to God and he will hear you, if you love and obey #yeshua.
