The Lord Almighty is the one to regard as holy, he is the one to fear

Isaiah 8:1-22
Isaiah name his son ,"Maher-Shalal-Hash-Bazz." For before the boy knows how to say 'May father or My mother, the wealth of Damascus and the plunder of Samaria will be carried off by the king os Assyria.
Because this people has rejected the gently flowing waters of Shiloah and rejoices over Rezin and the son Remaliah, therefor the Lord is about to bring against them the mighty flood waters of the Euphrates - the king of Assyria with all his pomp.
The Lord warning Isaiah not to follow the way of this people: Do not call conspiracy everything this people calls a conspiracy; do not fear what they fear, and do not dread it. The Lord Almighty is the one you are to regard as holy, he is the one you are to fear, he is the one you are to dread(可怕.)
Blind up this testimony of warning and seal up God's instruction among my disciples. I will wait for the Lord, who is hiding his face from the descendants of Jacob,. I will put my trust in him.
Why consult the dead on behalf of the living?
Consult God's instruction and the testimony of warning. If anyone does not speak according to this word, they have no light of dawn.
Maher-Shalal-Hash-Bazz : same message as "God with us' - one of judgment at the hands of Assyria.
Why?
God used a name of Isaiah's son as sign to warning his people. The judgment is coming soon.
When people reject God and his word, there are fear and dread coming soon.
Do not follow the way of this people, do not follow the custom of  contemporary culture. Fear the Lord and trust in Him is the way to Christians.
The Lord Almighty is the one I am to regard as holy, he is the one I am to fear. There is not dark in my life.
How?
Consult God's instruction and the testimony of warning.
