God addresses the Israelites’ religious practices in Isaiah 58 (selected verses from NLT). Sort of sounds like Jesus’ words about sheep and goats (Matthew 25:31-46 NLT), doesn’t it?
1“Shout with the voice of a trumpet blast.
Shout aloud! Don’t be timid.
Tell my people Israel of their sins!
2 Yet they act so pious!
They come to the Temple every day
and seem delighted to learn all about me.
They act like a righteous nation
that would never abandon the laws of its God.
They ask me to take action on their behalf,
pretending they want to be near me.
3 ‘We have fasted before you!’ they say.
‘Why aren’t you impressed?
We have been very hard on ourselves,
and you don’t even notice it!’
“I will tell you why!” I respond.
“It’s because you are fasting to please yourselves.
Even while you fast,
you keep oppressing your workers.
4 What good is fasting
when you keep on fighting and quarreling?
This kind of fasting
will never get you anywhere with me.
5 You humble yourselves
by going through the motions of penance,
bowing your heads
like reeds bending in the wind.
You dress in burlap
and cover yourselves with ashes.
Is this what you call fasting?
Do you really think this will please the Lord?
6 “No, this is the kind of fasting I want:
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.
9 Then when you call, the Lord will answer.
‘Yes, I am here,’ he will quickly reply.
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!”
Does it seem harsh? Maybe, but the One who sees the heart cannot be fooled.
