But we can't reach them and shouldn't try, even if they were capable of interceding on our behalf, and no one knows that they can do that.
Hmmmmm...Scripture seems to disagree...
9 When He opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony which they held. 10 And they cried with a loud voice, saying, “How long, O Lord, holy and true, until You judge and avenge our blood on those who dwell on the earth?” 11 Then a white robe was given to each of them; and it was said to them that they should rest a little while longer, until both
the number of their fellow servants and their brethren, who would be killed as they
were, was completed. (Rev 6:9-11)
3 Then another angel, having a golden censer, came and stood at the altar. He was given much incense, that he should offer
it with the prayers of all the saints upon the golden altar which was before the throne. 4 And the smoke of the incense, with the prayers of the saints, ascended before God from the angel’s hand (Rev 8:3-4)
It's a petition. If you pray to a saint, it's a request for intercession. Some people think they can mediate as well as intercede, but only Christ is our mediator.
