Here I am again with your simple (overly simple?) answer to a complicated question.
For real, I think sometimes we do overcomplicate things. Life, faith, love, and all good and true things should be approached with a childlike trust and dependence of our faithful God. Everything should be viewed through the eyes of wonder, because everything is far more miraculous than our overly rational and pragmatic minds have made them out to be.
So, let’s go:
The objection: How can you pray to the saints? They are not omnipresent! Only God is!
The answer: True, only God is everywhere at all time. But when I am fully united with him through the passage of my death, I will be able to more fully partake of his divinity, which could never be fragmented into parts. Jesus said, “that where I am you may be also.” (John 14:3)
The objection: How can you pray to the saints? They are not omniscient! They cannot know all things or even that you are praying to them.
The answer: While humans, on our own, are never omniscient, saints are fully united to him who is; they dwell within the One who knows all things.
The objection: How can you pray to the saints? They are not omnipotent! How can they help you?
The answer: God is omnipotent and is not limited in his power to work through humans. He can work through any means he chooses.
The objection: How can you pray to the saints? They are dead!
The answer: Ah! but they are alive in Christ, are they not? And to be fully united to Christ is the most alive a person could possibly be. One might go as far as to argue that the saints are more alive than we are here in this vale of tears.

What can I say? I am not a theologian. I’d rather be a mystic.
