True fasting is not what we’re eating, what we’re not eating or what we’re giving up. This is the kind of fast the Lord is pleased with- to free the chains of injustice, to treat your employees right, to free the oppressed, to feed the hungry, to provide shelter for the homeless, to clothe the naked and to help relatives in need.
And when you do these, God promises that your light shall break forth like the morning, your healing shall spring forth speedily, and your righteousness shall go before you; the glory of the LORD shall be your rear guard. Then you shall call, and the Lord will answer. Isaiah 58:8-9
