Peo­p­le live from God’s word – but the decisi­ve fac­tor is how we lis­ten. Jesus makes it clear: true hea­ring always leads to action. Tho­se who recei­ve God’s voice and live accor­din­gly build their lives on a firm foun­da­ti­on. Tho­se who only hear but do not act lose spi­ri­tu­al sub­s­tance. That is why the fol­lo­wing appli­es: hear, belie­ve, do – this is how God’s work in our lives beco­mes visible.


Emper­or Fre­de­rick wan­ted to find out the com­mon ori­gi­nal lan­guage of all peo­p­le. To dis­co­ver this, he star­ted a series of expe­ri­ments. He wan­ted to obser­ve in which lan­guage child­ren began to speak to whom no one had spo­ken befo­re. A chro­nic­le from the year 1268 reports: «And the­r­e­fo­re he com­man­ded the wet-nur­ses and nur­ses to give the child­ren milk, to bathe and wash them, but in no way to pret­ti­fy them or speak to them.» He was curious to see whe­ther the child­ren would speak Hebrew, Greek, Latin, Ara­bic or the lan­guage of their par­ents. But the attempt fai­led tra­gi­cal­ly: all the child­ren died.

On the out­side, they had ever­y­thing they nee­ded to live. Food, care, pro­tec­tion. And yet they died. Why? They lacked the most important things: the speech, the loving care, the spo­ken word.

This exam­p­le shows some­thing pro­found: Peo­p­le don’t just live from what they get – but from what they hear.

True hearing as the basis of life

«Man does not live by bread alo­ne, but by every word that comes from the mouth of the Lord» (Deu­te­ro­no­my 8:3 New Testament).

If we do not hear God’s voice, some­thing dies in us – per­haps not our body, but our faith. Our inner life beco­mes weak, power­less, emp­ty. It is the­r­e­fo­re cru­cial that we prio­ri­ti­se lis­tening to God’s voice.

But how does this hea­ring hap­pen? The Bible descri­bes it like this: «For you have not recei­ved a spi­rit of slavery, that you should fear again; but you have recei­ved a spi­rit of adop­ti­on, by which we cry out: Abba, dear Father! The Spi­rit hims­elf bears wit­ness to our spi­rit that we are child­ren of God.» (Romans 8:15f LUT).

God does­n’t just speak to us from the out­side – He speaks to our inner­most being. His spi­rit com­mu­ni­ca­tes with our spi­rit. Some­ti­mes God speaks in a very con­cre­te and gui­ding way. Some­ti­mes He com­forts us. Some­ti­mes He cor­rects us. But regard­less of the con­tent, each of His mes­sa­ges car­ri­es a deep, iden­ti­ty-forming truth: You are my bel­oved child.

As with the bap­tism of Jesus: «This is my bel­oved son, in him I have gre­at joy» (Matthew 3:17 NLB). This pro­mi­se always reso­na­tes when God speaks.

And that chan­ges ever­y­thing. When we not only know this truth, but accept it inward­ly, much of what bur­dens us loses its power. Worries, fears and inse­cu­ri­ties begin to rece­de when we know who we are in God’s eyes.

True hearing becomes visible

But that’s just the first step. It’s not just about what we hear – but how we hear. Jesus explains this impres­si­ve­ly in the para­ble of the sower in Luke 8:4–15. The seed is the word of God. The dif­fe­rent flo­ors repre­sent dif­fe­rent types of hea­ring:

  • Some hear, but the devil takes the word away.
  • Some lis­ten with joy, but have no root.
  • Some lis­ten, but worries and wealth stif­le the word.
  • Others hear, keep the word and bear fruit.

The seed is always good. It does not depend on the qua­li­ty of God’s word. The cru­cial ques­ti­on is: What is the soil of our heart like? As lis­ten­ers, we bear respon­si­bi­li­ty. Our heart must be rea­dy to recei­ve the word, to pre­ser­ve it and to allow it to grow.

Imme­dia­te­ly after­wards, Jesus uses ano­ther image: the light. «Nobo­dy would light a lamp and then put some­thing over it or put it under the bed. No, lamps are pla­ced whe­re ever­yo­ne who comes in can see them» (Luke 8:16 NLB).

This means that what God speaks into us should beco­me visi­ble. It is not meant to remain hid­den. True hea­ring does not remain invi­si­ble. It shows its­elf in life. The grea­test gift that Chris­ti­ans can give this world is not per­fect pro­gram­mes or impres­si­ve words – but peo­p­le who hear and are chan­ged by them.

Then Jesus gives a very serious war­ning: «So look now how you hearFor whos­oe­ver hath, to him shall be given; but whos­oe­ver hath not, from him shall be taken even that which he thinketh he hath» (Luke 8:18 LUT).

It’s not just about the fact that we hear – but how we hear. The­se words show two pos­si­ble developments:

  • Whoe­ver tru­ly accepts the word → will be given more.
  • Tho­se who don’t real­ly accept it → even lose what they think they have.

This is a war­ning against super­fi­ci­al lis­tening. We can hear God’s word, find it inte­res­t­ing, agree with it – and yet it remains incon­se­quen­ti­al. And that is pre­cis­e­ly what is dan­ge­rous. The Bible descri­bes this con­di­ti­on as spi­ri­tu­al dull­ness. Isai­ah 6:10 speaks of ears beco­ming dull of hea­ring. Inte­res­t­ingly, we are also fami­li­ar with this prin­ci­ple from psy­cho­lo­gy. Our brain has the abili­ty to habi­tua­te. We are con­stant­ly expo­sed to sti­mu­li. If we were to con­scious­ly per­cei­ve them all, we would be over­whel­med. Our brain the­r­e­fo­re lear­ns to block out unim­portant stimuli.

This can also hap­pen spi­ri­tual­ly. If we keep hea­ring but don’t act on it, our inner self lear­ns: «This has no con­se­quen­ces.» What we hear is cate­go­ri­sed as unimportant.

We lis­ten to ser­mons, read Bible texts, recei­ve impul­ses – but don’t put any of it into prac­ti­ce. And over time, some­thing dan­ge­rous hap­pens: We beco­me unre­cep­ti­ve. We still hear – but it no lon­ger rea­ches us.

Jesus puts it dra­sti­cal­ly in a nuts­hell: «But whoe­ver lis­tens to me and not is a fool; he is like a man who builds a house on sand» (Matthew 7:26 NLB).

True listening leads to action

So what does real, cor­rect hea­ring look like? Jesus ans­wers this ques­ti­on not only in theo­ry, but in prac­ti­ce. Luke 8:19–21 tells us that his mother and brot­hers come to him but can­not get through to him becau­se of the crowd. They say to him: «Your mum and brot­hers are out­side and want to see you» (Luke 8:20 NLB).

His ans­wer is sur­pri­sing: «My mother and my brot­hers are tho­se who hear and do God’s word» (Luke 8:21 LUT).

That is a radi­cal state­ment. It’s not about exter­nal pro­xi­mi­ty. Not about ori­gin. Not about reli­gious affi­lia­ti­on. This alo­ne is decisi­ve: Hea­ring God’s word – and acting accor­din­gly. This is how true disci­ple­ship is reco­g­nis­ed. A per­son who lis­tens like this is pro­mi­sed ama­zing things:

  • She belongs to the fami­ly of God. This reminds us that His Spi­rit testi­fies to our spi­rit that we are God’s children.
  • It bears visi­ble fruit – like a field that yields a hundred­fold (Luke 8:8).
  • And she builds her life on a firm foun­da­ti­on. This brings us full cir­cle to Matthew 7: the dif­fe­rence bet­ween rock and sand is asto­nis­hin­gly small – it is the litt­le word ’not». He who hears God’s word and does it is buil­ding on a rock, he who hears God’s word and does not do it is buil­ding on sand. Out­ward­ly, both can look simi­lar. But the dif­fe­rence beco­mes appa­rent in the storm.

The Bible makes it clear time and again that lis­tening and obey­ing belong inse­pa­ra­b­ly tog­e­ther. In the bibli­cal lan­guages, both are in the same word.

Abra­ham is an impres­si­ve exam­p­le of this. It is said about him: «Abram set out as the LORD had com­man­ded him» (Gene­sis 12:4 NLB). This is the core of his faith: he heard – and he went.

The let­ter to the Hebrews sum­ma­ri­ses it like this: «By faith, Abra­ham obey­ed when God told him to lea­ve his home­land and move to ano­ther land that God would give him as an inhe­ri­tance. He left wit­hout kno­wing whe­re his path would lead him»(Hebrews 11:8 NLB).

Abra­ham did­n’t always under­stand ever­y­thing. Many things did­n’t make sen­se. And yet he trus­ted God. This is shown most cle­ar­ly in the sto­ry in which he is asked to sacri­fice his son. After 25 years of wai­ting for the pro­mi­se, God asks him to take a step that is incom­pre­hen­si­ble to humans. And yet we read: «Abra­ham got up ear­ly the next mor­ning […] and set off for the place God had named to him.» (Gene­sis 22:3 NLB). Why? Becau­se he had lear­nt that God’s voice is trustworthy.

At important points in my life, God has spo­ken so cle­ar­ly into my life that the ques­ti­on is no lon­ger what God’s will is, but only whe­ther I am wil­ling to obey. If we want to build our lives on rock, the­re is no way around it. Of cour­se, the­re are also situa­tions in which we are uncer­tain. We don’t know exact­ly what God’s will is. Then we can act to the best of our know­ledge and belief and trust God to gui­de us.

True hea­ring is not an acou­stic pro­cess. It is an inner pro­cess that shapes our lives. We live from God’s word. We recei­ve our iden­ti­ty from it. And we show through our actions that we have tru­ly heard. In the end, it all boils down to this simp­le but chal­len­ging truth: It is not he who hears who grows – but he who hears and acts.

 

Possible questions for the small groups

Read the Bible text: Luke 8:4–21

  1. Whe­re have you recent­ly had the impres­si­on that God has spo­ken to you – and how have you dealt with it?
  2. Which «type of soil» (Luke 8) do you most reco­g­ni­se in your life at the moment – and why?
  3. Is the­re some­thing that you know God has shown you, but you haven’t rea­li­sed yet? What is stop­ping you?
  4. How can you make sure that what you hear is also visi­ble in your ever­y­day life?
  5. To be honest, are you curr­ent­ly buil­ding your life more on rocks or on sand – and how does that show in practice?
