In chapter 58 of the book of Isaiah we will review a little about the true fast, since the people of Israel fasted asking for justice to God and believing themselves worthy of God, but they had turned away from God after idolatry, had moved away from their laws, in short, they had rebelled totally before God. May the Lord free us from believing that we are well when deep down we know that we are bad and we deeply need God.
The Bible says speaking to the people of Israel:
3 ‘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.4 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.5 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?Isaiah 58:3-5
