Isa 58:2-4  "Yet they seek me daily and delight to know my ways, as if they were a nation that did righteousness and did not forsake the judgment of their God; they ask of me righteous judgments; they delight to draw near to God. 'Why have we fasted, and you see it not? Why have we humbled ourselves, and you take no knowledge of it?' Behold, in the day of your fast you seek your own pleasure, and oppress all your workers.  Behold, you fast only to quarrel and to fight and to hit with a wicked fist. Fasting like yours this day will not make your voice to be heard on high."

You cannot fool the Absolute Love, His love pierces through all pretense and deceit.There are real consequences to our actions, thoughts and intentions. Whether for our good or destruction, being enveloped in the light of love or the darkness of separation.
Isa 58:5-7  "Is such the fast that I choose, a day for a person to humble himself? Is it to bow down his head like a reed, and to spread sackcloth and ashes under him? Will you call this a fast, and a day acceptable to the LORD? "Is not this the fast that I choose: to loose the bonds of wickedness, to undo the straps of the yoke, to let the oppressed go free, and to break every yoke?  Is it not to share your bread with the hungry and bring the homeless poor into your house; when you see the naked, to cover him, and not to hide yourself from your own flesh?"

The result of walking in truth and righteousness out of love for God brings ultimate satisfaction. He is Absolute love.

Isa 58:8-11  "Then shall your light break forth like the dawn, and your healing shall spring up speedily; 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; you shall cry, and he will say, 'Here I am.' If you take away the yoke from your midst, the pointing of the finger, and speaking wickedness,  if you pour yourself out for the hungry and satisfy the desire of the afflicted, then shall your light rise in the darkness and your gloom be as the noonday. And the LORD will guide you continually and satisfy your desire in scorched places and make your bones strong; and you shall be like a watered garden, like a spring of water, whose waters do not fail."
