When on that evil day, in the spiritual realm

I can't find the post, but someone left a comment to a post I'd written wherein my post was talking about how the word of God becomes practical to a new degree when we die and are in battle with spiritual forces and so forth.

The comment writer wrote a typical, shallow: "Show where it says that in Scripture. Show it. Show where it says we will be in battle with spiritual forces when we die." He only didn't add: "Typical oogie boogie stuff!!"

I didn't answer him because I saw the comment about four months after he'd written it. But in reading the Book of Psalms today I was reminded of it.

Psalm 20 in particular reminded me of the challenge:

1 The LORD hear thee in the day of trouble; the name of the God of Jacob defend thee;
2 Send thee help from the sanctuary, and strengthen thee out of Zion;

That phrase, the day of trouble. I associate it with physical death. Ephesians 6:

13 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.

Day of trouble... Evil day. In Ephesians the context is the armor of God of course. Why do we need it? To stand in the evil day. To stand against what?

11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.

This is always, but 'the evil day' is singled out as well.

I discern Psalm 18 as well as describing physical death and the battle against spiritual forces that commences.

The word of God becomes practical in a new way then because what now seems overly simple or obvious takes on basic, foundational meaning in the spiritual realm. (It does *now* too, but I am speaking in particular of the day of physical death.)

Like for instance, the word of God will say, don't lie, tell the truth. In Proverbs somewhere, say. Well, we think, yes, that is pretty straight forward, simple advice. Yet in the spiritual realm it becomes something more, something practical to a specific event or encounter.

Fallen angels: "Who are you? Where do you think you are going?"

Fearful Christian: "I am someone who is just walking around. I don't mean any harm! Do you think I should turn back? I will!"

Now here is the scenario of a Christian who knows the word of God and fears God only:

Fallen angels: "Who are you? Where do you think you are going?"

Christian with bold truth: "I am a child of the living God, and a subject of my King Jesus Christ; and in fact I am a king myself, and a subject in good legal standing in the Kingdom of God by faith in the work and the voluntary death of my King in His life and on the cross. I have a swift horse and a deadly Sword, and I don't even plan on having to use this Shield. That's right, fly away. I'll see you at the final battle. Give my regards to your creepy leader. No, I have no sympathy for him, as some do. Zero."
