a word from Isaiah

So, if Isaiah speaks truth here, how then should we live?

Isaiah 58
6 Free those who are wrongly imprisoned;
  lighten the burden of those who work for you.
Let the oppressed go free,
  and remove the chains that bind people.
7 Share your food with the hungry,
  and give shelter to the homeless.
Give clothes to those who need them,
  and do not hide from relatives who need your help.

8 "Then your salvation will come like the dawn,
  and your wounds will quickly heal.
Your godliness will lead you forward,
  and the glory of the LORD will protect you from behind.
9 Then when you call, the LORD will answer.
  'Yes, I am here,' he will quickly reply.

"Remove the heavy yoke of oppression.
  Stop pointing your finger and spreading vicious rumors!
10 Feed the hungry,
  and help those in trouble.
Then your light will shine out from the darkness,
  and the darkness around you will be as bright as noon.
11 The LORD will guide you continually,
  giving you water when you are dry
  and restoring your strength.
You will be like a well-watered garden,
  like an ever-flowing spring.
12 Some of you will rebuild the deserted ruins of your cities.
  Then you will be known as a rebuilder of walls
  and a restorer of homes.

13 "Keep the Sabbath day holy.
  Don't pursue your own interests on that day,
but enjoy the Sabbath
  and speak of it with delight as the LORD's holy day.
Honor the Sabbath in everything you do on that day,
  and don't follow your own desires or talk idly.
14 Then the LORD will be your delight.
  I will give you great honor
and satisfy you with the inheritance I promised to your ancestor Jacob.
  I, the LORD, have spoken!"
