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.
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. 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!
And it is impossible to please God without faith. Anyone who wants to come to him must believe that God exists and that he rewards those who sincerely seek him.
You love him even though you have never seen him. Though you do not see him now, you trust him; and you rejoice with a glorious, inexpressible joy. The reward for trusting him will be the salvation of your souls.
