The Daniel Fast
21 days set apart to seek God.

What the Daniel Fast is
The book of Daniel opens with the first deportation from Judah to Babylon, in the third year of King Jehoiakim (around 605 BC). Nebuchadnezzar took young men from the nobility to be trained for three years in the language and culture of the Chaldeans, with new names and food from the king’s table. The text does not explain in detail why Daniel refused those delicacies; interpreters often point to the food laws given through Moses, and to the fact that eating from the royal table meant depending on the king and his gods. What the text does make clear is that the decision was born in the heart before it became a request.
The Daniel Fast, in this journey, is a 21-day season of consecration. Inspired by the text itself, it usually involves simple food, without the “delicacies” we have grown used to having on hand, and also abstaining from the excesses that crowd the heart: endless entertainment, scrolling through screens, the noise that never lets you be alone with God. The time and attention left over are given to prayer and to the Word. Fasting is not a coin to buy answers with; it is a way of saying, with your body and your calendar, that God comes first.
So before you begin, a word of care. If you have a health condition, take ongoing medication, are pregnant or breastfeeding, or have ever struggled with eating, talk to your doctor and adapt the fast. Consecration is not hurting yourself. You can fast from other things, such as social media, TV shows, impulse buying or late nights, and its worth before God remains the same, because he looks at a willing heart.
In the Bible
But Daniel purposed in his heart that he would not defile himself with the king’s delicacies, nor with the wine which he drank. Therefore he requested of the prince of the eunuchs that he might not defile himself.
“Test your servants, I beg you, ten days; and let them give us vegetables to eat and water to drink.
In those days I, Daniel, was mourning three whole weeks. I ate no pleasant food. No meat or wine came into my mouth. I didn’t anoint myself at all, until three whole weeks were fulfilled.
“Isn’t this the fast that I have chosen: to release the bonds of wickedness, to undo the straps of the yoke, to let the oppressed go free, and that you break every yoke?
But you, when you fast, anoint your head and wash your face, so that you are not seen by men to be fasting, but by your Father who is in secret; and your Father, who sees in secret, will reward you.

Day 1 · The decision to consecrate yourself
Today’s reading: Daniel 1:1-8
1In the third year of the reign of Jehoiakim king of Judah, Nebuchadnezzar king of Babylon came to Jerusalem and besieged it. 2The Lord gave Jehoiakim king of Judah into his hand, with some of the vessels of the house of God; and he carried them into the land of Shinar to the house of his god. He brought the vessels into the treasure house of his god. 3The king spoke to Ashpenaz, the master of his eunuchs, that he should bring in some of the children of Israel, even of the royal offspring and of the nobles: 4youths in whom was no defect, but well-favored, skillful in all wisdom, endowed with knowledge, understanding science, and who had the ability to stand in the king’s palace; and that he should teach them the learning and the language of the Chaldeans. 5The king appointed for them a daily portion of the king’s delicacies and of the wine which he drank, and that they should be nourished three years, that at its end they should stand before the king. 6Now among these of the children of Judah were Daniel, Hananiah, Mishael, and Azariah. 7The prince of the eunuchs gave names to them: to Daniel he gave the name Belteshazzar; to Hananiah, Shadrach; to Mishael, Meshach; and to Azariah, Abednego. 8But Daniel purposed in his heart that he would not defile himself with the king’s delicacies, nor with the wine which he drank. Therefore he requested of the prince of the eunuchs that he might not defile himself.

Context
The book of Daniel opens with the first deportation from Judah to Babylon, in the third year of King Jehoiakim (around 605 BC). Nebuchadnezzar took young men from the nobility to be trained for three years in the language and culture of the Chaldeans, with new names and food from the king’s table. The text does not explain in detail why Daniel refused those delicacies; interpreters often point to the food laws given through Moses, and to the fact that eating from the royal table meant depending on the king and his gods. What the text does make clear is that the decision was born in the heart before it became a request.
Daniel was young when everything was taken from him: his land, his home, the temple, even his name. In Babylon he came to be called Belteshazzar, to study another language and to be prepared to serve another king. The empire did not want only his work; it wanted his soul shaped from the inside, slowly, at the table.
It is against this backdrop that we find the phrase that opens this journey: Daniel purposed in his heart. Before any conversation with the chief of the eunuchs, before any dish was refused, there was a hidden place where he decided whom he belonged to. Consecration begins like that, with no audience. It was not his surroundings that changed Daniel; it was Daniel who decided not to be changed by his surroundings.
The Daniel Fast, in this journey, is a 21-day season of consecration. Inspired by the text itself, it usually involves simple food, without the “delicacies” we have grown used to having on hand, and also abstaining from the excesses that crowd the heart: endless entertainment, scrolling through screens, the noise that never lets you be alone with God. The time and attention left over are given to prayer and to the Word. Fasting is not a coin to buy answers with; it is a way of saying, with your body and your calendar, that God comes first.
So before you begin, a word of care. If you have a health condition, take ongoing medication, are pregnant or breastfeeding, or have ever struggled with eating, talk to your doctor and adapt the fast. Consecration is not hurting yourself. You can fast from other things, such as social media, TV shows, impulse buying or late nights, and its worth before God remains the same, because he looks at a willing heart.
Maybe you are starting these days tired, unsure of yourself, remembering other times you started and stopped. Daniel had no guarantees either. He did not know how the king would react, or whether his request would be granted. He simply decided. And the decision settled in his heart was what sustained him for decades in Babylon.
Notice also that Daniel was not alone. Hananiah, Mishael and Azariah made the same decision, and each one’s faithfulness strengthened the others. Consecration is not a solitary race. If you can, invite someone to walk with you through these days, or at least tell one trusted person what you have decided. Not to be seen, but to be held up when your resolve weakens.
Today is not a day for big promises. It is a day for an honest decision, made before God, in the place where no one sees. What are you setting apart for him in these 21 days? Write it down, say it out loud, surrender it. The rest of the journey will rest on this.
