Fas­ting is an often unfa­mi­li­ar but cen­tral spi­ri­tu­al exer­cise that Jesus requi­res of his fol­lo­wers. Jesus does not cri­ti­cise fas­ting its­elf, but rather a hypo­cri­ti­cal fast that is put on dis­play, and invi­tes us to a hid­den, joyful fast that is com­ple­te­ly focu­sed on the Father. Bibli­cal fas­ting means con­scious­ly abs­tai­ning from food in order to turn one’s who­le body towards God and wor­ship him. It is an expres­si­on of the atti­tu­de that Jesus is more important than even our most basic needs and can be redis­co­ver­ed as a spi­ri­tu­al rhythm.


In the Gos­pel of Matthew, chap­ter six, Jesus talks about three prac­ti­ces of pie­ty. Giving to the nee­dy, pray­er and fas­ting. Which of the­se three is the most for­eign to you? For me, and pro­ba­b­ly most peo­p­le in here, it’s fas­ting! What kind of cont­act have you had with fas­ting? I can count mine on one hand. The first memo­ry is from about seven to eight years ago. It was a time when I was doing inter­mit­tent fas­ting. I abs­tained from eating bet­ween 8pm and 12am. The aim was to lose weight and eat healt­hi­er. I did this for about six months. My second expe­ri­ence was about six months ago. I was short on time in the mor­ning. So I deci­ded to con­scious­ly spend time with God and skip breakfast.

How do you rela­te to fas­ting? What does the topic trig­ger in you? Fear? Shaking up bad expe­ri­en­ces or memo­ries? Fas­ting is wide­spread out­side the Wes­tern church and is prac­ti­sed by prac­ti­cal­ly all other reli­gi­ons. Fit­ness gurus fast. Various non-Jesus-cent­red spi­ri­tu­al move­ments fast. Parts of the Catho­lic Church fast. The Ortho­dox churches also fast.

Today’s ser­mon marks the start of a total of four ser­mons every fort­night. The last one will take place on 22 Febru­ary. On the one hand, the­se ser­mons are a pre­pa­ra­ti­on for Lent, which runs from 18 Febru­ary to 5 April. On the other hand, it is an impul­se to inte­gra­te fas­ting as a regu­lar rhythm in your week. In this series, you also have the oppor­tu­ni­ty to send me your ques­ti­ons, comm­ents and reac­tions via a You­Tube comment.

When you fast…

As I said, I am a com­ple­te novice in the field of fas­ting – as you might be too! Tog­e­ther we immer­sed our­sel­ves in the words of Jesus Christ about fas­ting. This made me per­so­nal­ly very «glus­tig». Jesus says: «When you fast, do not do it publicly like the hypo­cri­tes who go around pale and care­less­ly dres­sed so that peo­p­le will admi­re them for their fas­ting. I assu­re you: That is the only reward they will ever recei­ve for it» (Matthew 6:16 NLB). Jesus says «if»! He does­n’t say if you fast, but when! So he assu­mes that fol­lo­wers of Jesus fast! The Greek word here means to abs­tain from food.

Jesus is not cri­ti­cis­ing fas­ting as such, but the com­mon prac­ti­ce. He calls them hypo­cri­tes. As so-cal­led «hypo­cri­tes». The­se were ori­gi­nal­ly theat­re actors who por­tray­ed a cer­tain per­son behind a mask. This was then used col­lo­qui­al­ly and also in the con­text of the New Tes­ta­ment as an image for someone who pre­tends to be some­thing in their speech and actions that they are not. Peo­p­le pre­ten­ded to be out­ward­ly bland so that they could come out shi­ning by fasting.

Just as Jesus gives ins­truc­tions a few ver­ses ear­lier on how to pray pro­per­ly, he does the same for fas­ting. «When you fast, comb your hair and wash your face» (Matthew 6:17 NLB). In other words: Behave as you always do! Howe­ver, this state­ment by Jesus makes a pro­found state­ment about fas­ting based on the cul­tu­re of the time. It lite­ral­ly says «anoint your head». Anoin­ting was a sign that the time of mour­ning was over and that the­re was now a reason to cele­bra­te (2 Samu­el 12:20). So what Jesus is say­ing here is that fas­ting is not a time of mour­ning, but rather a reason to celebrate.

Why does Jesus say that we should fast? «Then no one will think that you are fas­ting except your Father, who knows what you are doing in silence. And your Father, who knows all secrets, will reward you for it» (Matthew 6:18 NLB). Fas­ting is based on a basic spi­ri­tu­al ori­en­ta­ti­on: towards the Father! Mar­tin Luther, the Ger­man refor­mer, the­r­e­fo­re says: «If you want to fast pro­per­ly, remem­ber that you must first be a pious man» (Mar­tin Luther). Being a child of God means ori­en­ta­ting mys­elf towards the Father, making him the best of my life and sub­or­di­na­ting ever­y­thing to him! Ano­ther reason for fas­ting: the­re is a reward! But we are not told what kind. I think it’s about a chan­ged heart.

What fasting is not and what it is!

Befo­re we look at what fas­ting is in a bibli­cal con­text, I want to say a few things about what it is not. Fas­ting is not just giving up cer­tain habits. Mobi­le pho­ne fas­ting or social media fas­ting. Abs­tai­ning from alco­hol, meat, Dani­el fas­ting. Fas­ting in the bibli­cal sen­se means abs­tai­ning from eating and some­ti­mes even drin­king! Abs­ti­nence from cer­tain things is good, but is not what is meant by bibli­cal fasting.

The­re are also many non-reli­gious moti­ves for fas­ting. It can include ever­y­thing from self-con­trol to health exer­cise, pro­test, trans­for­ma­ti­on, gai­ning know­ledge and expres­sing auto­no­my. It is the­r­e­fo­re important to know why you are fas­ting and for what purpose!

Food is not sim­ply bad, but abso­lut­e­ly posi­ti­ve. Bread and gra­pe juice in par­ti­cu­lar remind us of Jesus Christ. But the­re is more than food. Jesus says: «[…] Scrip­tu­re says that man needs more than bread to live. He also lives by every word that comes from the mouth of God» (Matthew 4:4 NLB). He says this after 40 days of fas­ting in the desert when he was tempt­ed by the devil. We often have the impres­si­on that the devil encoun­ters him in his time of grea­test weak­ne­ss. But what if Jesus was here in his time of grea­test strength! Not despi­te fas­ting, but becau­se of it!

Fas­ting is the prac­ti­ce of God that brings our rela­ti­onship with food and our body, inde­ed our who­le per­son, into cont­act with God! The Bible distin­gu­is­hes bet­ween two types of fas­ting. On the one hand, it is a respon­se to attacks, los­ses, etc. On the other hand, as a rhythm (Levi­ti­cus 23:27). Abo­ve all, the goal is decisi­ve! It is about wor­ship! Fas­ting is a focus­sed devo­ti­on to God.

Jesus the bread of life

«Jesus repli­ed: «I am the bread of life. Whoe­ver comes to me will never hun­ger again. Whoe­ver belie­ves in me will never thirst again» (John 6:35 NLB). Jesus Christ is the bread of life. But are we hun­gry for him? Hun­ger is the fee­ling of wan­ting or nee­ding some­thing we don’t have. When we fast, we sacri­fice our who­le body to God!

Who has alre­a­dy come across Maslow’s pyra­mid of needs? This ranks needs accor­ding to their importance and starts with basic sur­vi­val needs through to the need for self-actua­li­sa­ti­on. The idea is that needs increase from the bot­tom to the top. The less a lower need is ful­fil­led, the less peo­p­le gene­ral­ly stri­ve for a hig­her need. Abs­tai­ning from food and expe­ri­en­cing hun­ger starts at the lowest level. It is a basic need. Wit­hout satis­fy­ing this, ever­y­thing else is secon­da­ry. Fol­lo­wers of Jesus say exact­ly this: Jesus is the most important thing in their lives. Ever­y­thing else is secon­da­ry! Fas­ting is an expres­si­on of this attitude.

Fas­ting is no lon­ger «IN». We have lost the theo­lo­gy of the body. This says that we not only have a body, but that we are a body! «I exhort you the­r­e­fo­re, brot­hers and sis­ters, by the mer­ci­es of God, that you pre­sent your bodies a living sacri­fice, holy and accep­ta­ble to God. Let this be your reasonable wor­ship» (Romans 12:1 LUT). Many Bibles trans­la­te this as «your life». But the empha­sis is expli­cit­ly on the body! Here we are again very clo­se to last year’s ser­mon series on «Faith & Body». The aim of fas­ting is to wor­ship Jesus Christ with our who­le body. This is not easy, so fas­ting con­fronts us with our weak­ne­ss. We are not com­man­ded to fast any­whe­re, but many Bible cha­rac­ters, inclu­ding Jesus, fasted.

But what now? A warm invi­ta­ti­on to fast. It would be nice if all your thoughts did­n’t just remain in your head, but also ente­red your body. Think about whe­re and how you could fast. For exam­p­le, replace a meal with an encoun­ter with God. Fast for 24 hours. From get­ting up to sun­set. Important with all the­se thoughts: start whe­re you are, not whe­re you want to be! Use the time that would be rela­ted to food to wor­ship God (shop­ping, coo­king, eating). If it is not pos­si­ble for you to fast for cer­tain reasons (health, spe­cial situa­ti­on, job), then start with abs­ti­nence. As I said, not neces­s­a­ri­ly fas­ting, but a first step!

Possible questions for the small group

Read the Bible text: Matthew 6:16–18

  1. Which of the three devo­ti­ons from Matthew 6 (giving to the nee­dy, pray­er, fas­ting) is most ali­en to you per­so­nal­ly – and why? What expe­ri­en­ces or imprints play a role in this?
  2. What does the topic of fas­ting spon­ta­neous­ly trig­ger in you? Rather curio­si­ty, resis­tance, fear, indif­fe­rence – whe­re could the­se fee­lings come from?
  3. Jesus says: «If you fast …» (Matthew 6:16). What does this natu­ral­ness of fas­ting do to your image of discipleship?
  4. Why does Jesus attach so much importance to fas­ting being hid­den and not on show? What dan­ger does he see – and what could it look like today?
  5. In the ser­mon, fas­ting was descri­bed as some­thing joyful and wor­shipful. How does this per­spec­ti­ve fit in with your pre­vious under­stan­ding of fasting?
  6. Fas­ting con­fronts us with our basic needs and our depen­den­cy. What could fas­ting make visi­ble or reor­ga­ni­se in your life?
  7. What could be a rea­li­stic, con­cre­te next step for you? (e.g. skip­ping a meal, a 24-hour fast, con­scious abs­ti­nence) – and how could you spe­ci­fi­cal­ly use this time for God?
