True Fasting
“Shout it aloud, do not hold back. Raise your voice like a trumpet. Declare to my people their rebellion and to the descendants of Jacob their sins. For day after day they seek me out; they seem eager to know my ways, as if they were a nation that does what is right and has not forsaken the commands of its God. They ask me for just decisions and seem eager for God to come near them. ‘Why have we fasted,’ they say, ‘and you have not seen it? Why have we humbled ourselves, and you have not noticed?’
“Yet on the day of your fasting, you do as you please and exploit all your workers. Your fasting ends in quarreling and strife, and in striking each other with wicked fists. You cannot fast as you do today and expect your voice to be heard on high. Is this the kind of fast I have chosen, only a day for people to humble themselves? Is it only for bowing one’s head like a reed and for lying in sackcloth and ashes? Is that what you call a fast, a day acceptable to the Lord?
“Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke, to set the oppressed free and break every yoke? Is it not to share your food with the hungry and to provide the poor wanderer with shelter— when you see the naked, to clothe them, and not to turn away from your own flesh and blood? Then your light will break forth like the dawn, and your healing will quickly appear; then your righteousness will go before you, and the glory of the Lord will be your rear guard. Then you will call, and the Lord will answer; you will cry for help, and he will say: Here am I.
“If you do away with the yoke of oppression, with the pointing finger and malicious talk, and if you spend yourselves in behalf of the hungry and satisfy the needs of the oppressed, then your light will rise in the darkness, and your night will become like the noonday. The Lord will guide you always; he will satisfy your needs in a sun-scorched land and will strengthen your frame. You will be like a well-watered garden, like a spring whose waters never fail. Your people will rebuild the ancient ruins and will raise up the age-old foundations; you will be called Repairer of Broken Walls, Restorer of Streets with Dwellings.
— Isaiah 58:1-12
Submit yourselves, then, to God. Resist the devil, and he will flee from you. Come near to God and he will come near to you. Wash your hands, you sinners, and purify your hearts, you double-minded. Grieve, mourn and wail. Change your laughter to mourning and your joy to gloom. Humble yourselves before the Lord, and he will lift you up.
— James 4:7-10
Blessed is the one whose transgressions are forgiven, whose sins are covered. Blessed is the one whose sin the Lord does not count against them and in whose spirit is no deceit. When I kept silent, my bones wasted away through my groaning all day long. For day and night your hand was heavy on me; my strength was sapped as in the heat of summer. Then I acknowledged my sin to you and did not cover up my iniquity. I said, “I will confess my transgressions to the Lord.” And you forgave the guilt of my sin. Therefore let all the faithful pray to you while you may be found; surely the rising of the mighty waters will not reach them.
— Psalm 32:1-6
