Isaiah 27-29: A Sure Foundation

What does it mean to be just and righteouess?  Did Isaiah see that God's justice and righteouessness is a lot different from that which man would devise. 

For it is:
Do and do, do and do,
rule on rule, rule on rule;
a little here, a little there." - Is.28:10 NIV
 
So this is what the Sovereign LORD says:
"See, I lay a stone in Zion, a tested stone,
a precious cornerstone for a sure foundation;
the one who trusts will never be dismayed.
I will make justice the measuring line
and righteousness the plumb line;
hail will sweep away your refuge, the lie,
and water will overflow your hiding place. - Is. 28:16-17 NIV

The Lord says:
"These people come near to me with their mouth
and honor me with their lips,
but their hearts are far from me.
Their worship of me
is made up only of rules taught by men.
Therefore once more I will astound these people
with wonder upon wonder;
the wisdom of the wise will perish,
the intelligence of the intelligent will vanish."
Woe to those who go to great depths
to hide their plans from the LORD,
who do their work in darkness and think,
"Who sees us? Who will know?"
You turn things upside down,
as if the potter were thought to be like the clay!
Shall what is formed say to him who formed it,
"He did not make me"?Can the pot say of the potter,
"He knows nothing"?  - Is. 29:13-16

It wasn't just in Isaiah's generation that things were turned upside down. If we could see ourselves as God sees us, we would see that our righteousness is as filthy rags:  our worship is merely repetitious, we treat God as if he were our creation rather than the creator.  Our 'do and do, do and do, rule on rule, rule on rule'; or as the King James puts it 'precept upon precept, line upon line' is merely applying lip service, while at the same time we would place a heavy burden of 'do and do' on our fellow brothers and sisters.  Righteousness is not just following the rules.  It is not just clean living.  It is not just singing the right songs.  It is not just giving to the right organizations.  Righteousness comes from falling on that precious cornerstone, the sure foundation that has been given to us.  Falling and trusting because there is no other alternative.
