“The kind of fasting I want is that you stop oppressing those who work for you and treat them fairly and give them what they earn. I want you to share your food with the hungry and bring right into your own homes those who are helpless, poor and destitute. Clothe those who are cold and don’t hide from relatives who need your help. If you do these things, God will shed his own glorious light upon you. He will heal you; your godliness will lead you forward, and goodness will be a shield for you, and the glory of the Lord will protect you from behind. Then, when you call, the Lord will answer. “Yes, I am here”, he will quickly reply. All you need to do is to stop oppressing the weak and to stop making false accusation since spreading vicious rumors!
Feed the hungry! Help those in trouble! Then your light will shine out from the darkness, in the darkness around you shall be as bright as day. And the Lord will guide you continually, and satisfy you with all good things, and keep you healthy too; and you will be like a well-watered garden, like an ever-flowing spring. Your sons will rebuild the long-deserted ruins of your cities, and you will be known as “the people who rebuild their walls and cities”.”
Isaiah 58:6-12 (TLB)
