Delay of the faithful

Isaiah 30:1 “Stubborn children,” declares the Lord, “who carry out a plan, but not mine, and who make an alliance, but not of my Spirit, that they may add sin to sin; who set out to go down to Egypt, without asking for my direction, to take refuge in the protection of Pharaoh and to seek shelter in the shadow of Egypt! Therefore shall the protection of Pharaoh turn to your shame, and the shelter in the shadow of Egypt to your humiliation
God had allowed Assyria to be a dominant nation and under them Babylon as the enforcers. Israel were the representatives of the Covenant God – a covenant of protection and goodness. He was not only God over Israel as a nation but he was God over all nations. But instead of trusting in this covenant, they were ready to make a covenant with Egypt (a covenant with death).
In Biblical language going down to Egypt means trusting in the Kingdom of the world instead of in the kingdom of God. ( Abraham Genesis 12, Isaac Genesis 26)
For Christians that means trusting in self and not in God and His covenant.
15. For thus says the Lord God, the Holy One of Israel: “In returning and rest you shall be saved; In quietness and confidence shall be your strength.”But you would not, And you said, “No, for we will flee on horses”—Therefore you shall flee! And, “We will ride on swift horses”—Therefore those who pursue you shall be swift! One thousand shall flee at the threat of one, At the threat of five you shall flee, Till you are left as a pole on top of a mountain And as a banner on a hill.
But God Will Be Gracious Therefore the Lord will wait, that He may be gracious to you; And therefore He will be exalted, that He may have mercy on you. For the Lord is a God of justice; Blessed are all those who wait for Him. For the people shall dwell in Zion at Jerusalem; You shall weep no more. He will be very gracious to you at the sound of your cry; When He hears it He will answer you.
And though the Lord gives you The bread of adversity and the water of affliction,
Yet your teachers will not be moved into a corner anymore, But your eyes shall see your teachers. Your ears shall hear a word behind you, saying,“This is the way, walk in it,” Whenever you turn to the right hand or you turn to the left.
As a Christian you are a representative of His New Covenant, just as Israel was the representative of the Old Covenant. They knew it front to back and inside out, every blessing and every curse, every ordinance and law and penalty.
The Old Covenant had outward promises and blessings, like God winning battles for them to take the territory he had promised them, and prospering them by sending them rain for their crops and harvests. It is a very rewarding covenant for those who like outward blessings, but it is an incredibly demanding covenant when it comes to outward performance and sacrifice. It is full of blessings and curses, whereas the New covenant has only blessings and no curses – except for one – the curse of the LAW. The old covenant was not dependent upon faith but on obedient work. Faith is mentioned TWICE in the Old covenant. (Deuteronomy 32.20, Habakkuk 2:4). And faith is always blessed by God.
The blessings of the New Covenant are inward blessings, spiritual blessings (Ephesians 1:x). That is because the Kingdom is an inward kingdom, dependant upon obedient faith. So what about material blessings and our temporal needs? The answer is simple;
Matthew 6:33 Seek first the kingdom of God and all these things will be added to you.
What about performance and obedience and understanding? What about knowing the words of the covenant front to back and inside out? (Hosea 4:1
