Series: | Bible text: Luke 6:43–45
Hint: This ser­mon has been machi­ne trans­la­ted. Plea­se note that we can­not accept any respon­si­bi­li­ty for the accu­ra­cy of the content.

Our words have power. They can build peo­p­le up and encou­ra­ge them, but they can just as easi­ly hurt and dis­cou­ra­ge them. Often, the things we say reve­al more about our­sel­ves than we rea­li­se – becau­se our words come from our hearts. What we say reve­als what mat­ters to us, who we are and what we base our lives on. That is why it is worth taking a clo­ser look: what fills our hearts – and how can our words be incre­asing­ly shaped by Jesus?


On avera­ge, a per­son speaks 13,000 words a day. This was the fin­ding of a stu­dy that ana­ly­sed audio files from 2,197 peo­p­le. And yes, sta­tis­ti­cal­ly spea­king, it is true that women speak more than men – on avera­ge, around 1,500 more words a day. Howe­ver, the grea­ter varia­ti­on lies in indi­vi­du­al dif­fe­ren­ces – ran­ging from 100 to 120,000 words a day! Dif­fe­rent gene­ra­ti­ons also speak dif­fe­rent amounts. Young peo­p­le (aged 10–17) speak around 8,900 words. Young adults (aged 18–24) say around 12,200 words. Adults (aged 25–64) say around 16,500 words. Older adults (aged 65+) say around 9,450 words. So we have bet­ween 100 and 120,000 oppor­tu­ni­ties every day to make a dif­fe­rence – for bet­ter or for worse!

Simplicity

As with ever­y­thing we’re loo­king at this year, the main aim isn’t what we’re tal­king about, but rather being clo­se to Jesus and beco­ming like him! Prac­ti­sing sim­pli­ci­ty isn’t an end in its­elf, but a means to an end. When we con­sider sim­pli­ci­ty, the ques­ti­on is: «What does my heart pos­sess?» Pos­ses­si­ons are a very important topic here, but I’ll only touch on them very brief­ly in the next ser­mon. If you’re inte­res­ted in this topic, feel free to look up the series on pos­ses­si­ons and faith from just under a year ago.

At its core, sim­pli­ci­ty is about the ques­ti­on of iden­ti­ty. Who am I? What defi­nes me? Who deter­mi­nes my worth? Choo­sing sim­pli­ci­ty for our­sel­ves forces us not to make our iden­ti­ty depen­dent on exter­nal things! The oppo­si­te of sim­pli­ci­ty is not com­ple­xi­ty. Our lives in today’s world are com­plex, and this does not sim­ply dimi­nish when we live more sim­ply. The oppo­si­te of a life cha­rac­te­ri­sed by sim­pli­ci­ty is a shal­low, insi­pid, super­fi­ci­al life.

In this series of ser­mons, we’ll be explo­ring three the­mes, all of which rela­te to the human heart. Today we’ll start with lan­guage, as it is the direct link to our hearts. Next Sun­day we’ll be tal­king about clo­thes. As the say­ing goes: «Clo­thes make the man.» Our rela­ti­onship with clot­hing has a lot to do with our hearts. The final ser­mon will be about the sim­pli­ci­ty of enjoy­ment. We want to set out in search of true enjoyment.

Heart

«Abo­ve all, guard your heart, for your heart influen­ces your who­le life» (Pro­verbs 4:23 NLB). The human heart is unders­tood to be the seat of human thoughts (mind), will­power, emo­ti­ons and the sen­se of right and wrong (con­sci­ence). It is not mere­ly an ana­to­mic­al pump, but the very cent­re of a per­son! Our lan­guage is roo­ted the­re! It reve­als what mat­ters to us! How we think! Who we are!

Lan­guage always does this: whe­ther we’re under pres­su­re, with our fami­ly, at a mee­ting with the bank to dis­cuss a mor­tga­ge, in a job inter­view, when tal­king to our supe­ri­ors, on Insta­gram, or in con­ver­sa­ti­ons at church. It reve­als who we are! Depen­ding on the situa­ti­on, lan­guage flat­ters, pro­vo­kes, con­fronts, encou­ra­ges, glos­ses over things, and so on. It reve­als the image we’d like to project!

The heart is incre­di­bly important. Becau­se «A good tree can­not bear bad fruit, nor can a bad tree bear good fruit. A tree is reco­g­nis­ed by its fruit. Figs do not grow on thorn bus­hes, nor do gra­pes grow on bramble bus­hes.» (Luke 6:43–44 NLB). A good tree is good by its very natu­re. This is also evi­dent from its fruit. What, then, is meant by ‘fruit’? It refers to the effects of a person’s life. This is evi­dent in their words, in their deeds, and in the results that follow.

Now let us take a clo­ser look at the key ver­se, ver­se 45. «A good per­son brings forth good things from the good tre­asu­re of their heart, and an evil per­son brings forth evil things from the evil tre­asu­re; for out of the abun­dance of the heart the mouth speaks» (Luke 6:45 ELB). This ver­se tells us two things about the human heart. First­ly, it is a tre­asu­re, some­thing of immense poten­ti­al and value. Second­ly, it is unfa­thomable. The abun­dance of the heart shows that count­less thoughts and fee­lings lie hid­den the­re. Just watch a cou­ple new­ly in love (of any age).

There’s no doubt about the sheer volu­me of thoughts and fee­lings! But whe­ther it is a valuable tre­asu­re – that is the key ques­ti­on. Wha­te­ver I focus on and enga­ge with shapes my heart! I recent­ly noti­ced just how sexu­al­ly char­ged most of our films and TV series are. When I enga­ge with them, it influen­ces my thin­king. In the church whe­re I grew up, the­re was an Eng­lish-spea­king fami­ly who said they never lis­ten­ed to the radio at home becau­se there’s so much Eng­lish-lan­guage music on, and their child­ren under­stand it and start tal­king like that. Back then I laug­hed – but not any more. Every now and then, out of inte­rest, I brow­se pro­per­ty web­sites. The more I do this, the more the thought takes hold that we abso­lut­e­ly must have a house of our own! With the many apps on my smart­phone, I can track chan­ges to my pen­si­on pot every day. I quick­ly rea­li­se how fears about the future are begin­ning to take hold.

Plea­se note: Don’t say: ‘Can­cel your Net­flix sub­scrip­ti­on, lis­ten only to Chris­ti­an music, don’t buy your own home, don’t invest in the future.’ What I’m try­ing to empha­sise here is this: what I spend my time on shapes who I am! Inevitably!

Language

To stick with the image of the tree: the fruit is ine­vi­ta­ble. The ques­ti­on is whe­ther it is good or evil. And this ques­ti­on is deci­ded in the heart. It depends on what mat­ters to you! It’s about who you are! If your worth depends on cer­tain things, you’ll do ever­y­thing you can to hold on to them. If your worth depends on what God says about you, you’ll do ever­y­thing you can to honour Him. How can you tell if some­thing else is important to you in your heart? Watch your lan­guage! Your lan­guage gives you away! Always! Do I want to impress someone? «Sor­ry, I didn’t mean it that way» – but (if we’re honest with our­sel­ves)! Do I want to feel bet­ter about mys­elf? Am I only thin­king of myself?

Today’s ser­mon is an invi­ta­ti­on to make your speech part of your fol­lo­wing of Jesus. This appli­es to some more than others. I’m con­side­red very extro­ver­ted, and peo­p­le like me cer­tain­ly face a grea­ter chall­enge in this regard.

Becau­se when we talk about lan­guage – it’s also about spea­king less. That is the first point. Spea­king less means sin­ning less. «Do not speak too much, for that leads to sin. Be wise and hold your ton­gue!» (Pro­verbs 10:19 NLB). Sin means miss­ing the mark. The aim is to honour God with my words! Sin means miss­ing the mark. The aim is to honour God with my words. Hence this pie­ce of advice: if I speak less, I am also less likely to say things that do not meet this aim. Moreo­ver, peo­p­le actual­ly lis­ten to us when we are not con­stant­ly tal­king our­sel­ves. Fur­ther­mo­re, we crea­te space for others to speak. Many peo­p­le, mys­elf included, want to be inte­res­t­ing. What if, ins­tead, we were inte­res­ted in others?

Second­ly, it is important to speak the truth. It is clear to many that we should not tell lies. Yet it often hap­pens that we do not tell the who­le truth, lea­ving things out or glos­sing over them. Gene­ral­ly spea­king, we lie for two reasons: «I’m afraid» or «I want to». That is why it is important to be clear in our speech. To say what we mean, not to mani­pu­la­te. «Just say »Yes” or “No”. Any­thing more than that comes from the evil one.’ (Matthew 5:37 NLB).

Last but not least, we must use our words to bless, not to cur­se. Do not repay evil with evil. «If you are per­se­cu­ted becau­se you belong to Christ, do not cur­se your per­se­cu­tors, but ask God to bless them» (Romans 12:14 NLB).

This ver­se ser­ves as a useful gui­ding prin­ci­ple when con­side­ring how one should speak. «Refrain from idle talk, but let what you say be good and uplif­ting to others, so that they may be encou­ra­ged in their faith»(Ephe­si­ans 4:29 NLB). Here, the word used for «bad» is the same as that used for bad fruit: rot­ten, spoi­led. Our words should build up, not tear down; they should encou­ra­ge, not dis­cou­ra­ge; they should point to God.

You’re warm­ly invi­ted to think about what you’re going to do next week. The aim isn’t this exer­cise its­elf. Rather, the aim is to make room for Jesus in my own lan­guage. Try­ing to speak as Jesus did will ine­vi­ta­b­ly draw us into his embrace. For if I long for his influence to shape my life, then I will enga­ge with him!

Possible questions for the small group

Read the Bible pas­sa­ge: Luke 6:43–45

  1. Which state­ment or thought from the ser­mon has real­ly stuck with you – and why?
  2. Luke 6:45 says: «For out of the abun­dance of the heart the mouth speaks.» In your opi­ni­on, what does your speech reve­al about your heart? Is the­re any­thing you have ever rea­li­sed about yours­elf through your own words?
  3. In what situa­tions do you find that your words «just pour out» par­ti­cu­lar­ly quick­ly? For exam­p­le, when you’re stres­sed, with your fami­ly, during con­flicts, at work or online.
  4. Which of the­se three points do you find most chal­len­ging: spea­king less, spea­king the truth, or bles­sing others with your words? Why this one in particular?
  5. Are the­re any words that someone once said to you that still shape you today – for bet­ter or for worse? What made tho­se words so powerful?
  6. What is par­ti­cu­lar­ly clo­se to your heart at the moment? Which peo­p­le, media, con­ver­sa­ti­ons, thoughts or topics are sha­ping you – and how might that affect the way you speak?
  7. If you’d like to make more room for Jesus in your dai­ly life: what’s one spe­ci­fic step you’d like to try this week? For exam­p­le, lis­tening more atten­tively, spea­king less, addres­sing some­thing honest­ly, encou­ra­ging someone, or refrai­ning from giving a hurtful reply.
