Writing on the Walls Lyrics Meaning

I think it is a prayer...a person talking to God...he says

"Maybe we, why don't we? Sit right here for half an hour?"
Like if he wanted to say
"Hey God sit here with me to talk for some time "
And he part where he says
"And we'll speak of what a waste i am"
Means that he is telling God that he is not worth to be with him, but even like that God is with him, and the last part he says
"And how we missed your beat again"
Like if he had sinned, and feeling dirty because of it, thinking God left him because of it so he is worried, and afterwards he also question humanity.

"How come you try and,
(That brings us home)
To fit the shape of
(I pray for)
What they tell you
(you to move on, move on)
But mostly what they show you

This part he is questioning humanity for they try to fit and shape the word of God at their will, and not to preach about the truth, and so they take the easier path AKA the world.

At this rate, we cant keep up,
(I'm thinking back on the things I said) 2x
But I sure can't just sit still
Keep me filled in, I swear I'll come"

And that shows one of them thinking back the lies he had told to everyone, and how he shaped the words of God for his own use and then he is asking for forgiveness asking God to keep him filled with his spirit, and then he will do things right now without lies. and the next part is:

"We walk alone
Back home
Alone
Back home"

The "Home" here is heaven or the church, for though "We walk alone" has ambiguous meaning for one cannot walk alone if he is with someone else so the "WE" means more than one people As one like God and the person as one, one person but God, holy spirit and Jesus.

"You’re almost gone and I’m ok
(I still see your shadow)
To give you time to be afraid
(But never your face again
I remember your presence)"

The first line means that We are nothing without God but God is still GOD (OK) without us, it says he still see his shadow, that is things are not as they used to be, they are fading, "to give you time to be afraid" means that the person is dying because it denied God's truth, he still see his shadow, remember his presence, but is afraid, and will never see God again.

"I hope to God, you come down
I hope to God you can feel this now
I hope to God, you come down
I hope to...(God)..."

Is the prayer of someone that thinks God forgot him/her and wants God to feel their pain, and the feelings they feel, but they are not aware of the Bible or the words of God that says God forgave every sin by the price of blood, and the only thing they can hope at that time is for God nothing more.

"I know there must be some way out of here
And all of them will be waiting there"
Some way put of here means someone that is revolted with their situation and are full of living in fear, so they start searching for God and for solution to him and to everyone else, those are the valiant of heart that God chose and for the end "All of them will be waiting there" That part have two meanings for me, The first is, And all of the angels and people in heaven will be waiting there for you, or means that The people chosen by God will never fade, but all of them will be waiting there, for each one of us, to save us and show us the truth.

Thanks for your attention.
