Words, but also thoughts, have power: they can build us up or des­troy us, heal us or hurt us (Pro­verbs 18:21). That is why it is cru­cial what we think about throug­hout the day. With the help of the Holy Spi­rit, we learn to reco­g­ni­se fal­se thoughts and replace them with truths from the living Word of God.


«Have you washed your hands?» – We all know this phra­se. It is esti­ma­ted that par­ents ask their child this ques­ti­on bet­ween 5,000 and 30,000 times during child­hood. And for good reason: washing hands is important. It helps to remo­ve harmful bac­te­ria and viru­s­es that can dama­ge our bodies. In this way, we pre­vent patho­gens from ente­ring our orga­nism via our hands. Our socie­ty atta­ches gre­at importance to köPhy­si­cal hygie­ne – and that’s a good thing. But just as important is the Men­tal hygie­ne. What do I mean by that? Men­tal hygie­ne means that we con­scious­ly take care of our thoughts – just as we clean our hands.

How do you feel about yours­elf? This ques­ti­on is high­ly rele­vant not only phi­lo­so­phi­cal­ly, but also spi­ri­tual­ly and psy­cho­lo­gi­cal­ly. After all, our thoughts shape our iden­ti­ty, influence our decis­i­ons – and even affect our phy­si­cal health.

The Bible speaks again and again about how important it is to guard our inner sel­ves, to exami­ne our thoughts and to accept God’s view of us. Wrong thoughts can not only put a strain on our body, but also have a nega­ti­ve impact on our envi­ron­ment. Thoughts have power – they can build us up or wea­k­en us, heal us or hurt us. «Words have power: they canöcan deci­de over life and death. Tho­se who like to talköIf you do, you have to live with the con­se­quen­ces» (Pro­verbs 18:21 HfA). This Bible ver­se shows us the enorm­ous power of words. What we say does not remain wit­hout con­se­quen­ces – we will expe­ri­ence the fruits of our words. Tho­se who «like to hear them­sel­ves talk» will soo­ner or later be con­fron­ted with the con­se­quen­ces of their state­ments. But not only words, thoughts also car­ry power. Thoughts are like silent words that con­stant­ly accom­pa­ny us – and they have an impact on our lives. It is the­r­e­fo­re cru­cial – espe­ci­al­ly for par­ents – that we pass on healt­hy and truthful thoughts. In times of social media, we, our child­ren and young peo­p­le, are con­stant­ly fal­ling into the vic­tim role: «I’m not as cool, not as rich, not as pret­ty, not as strong. Ever­yo­ne else has more and is better.»

Today we want to dis­co­ver tog­e­ther how good thoughts about our­sel­ves not only streng­then our spi­ri­tu­al life, but also pro­mo­te our emo­tio­nal and phy­si­cal health.

God’s thoughts about you

«For I know the thoughts that I have toward you, says the LORD, thoughts of peace and not of sor­row, to give you a future and a hope» (Jere­mi­ah 29:11 LUT). This ver­se is a key to a healt­hy self-image. God thinks Good about you. His thoughts are Peaceful, hop­eful and future-ori­en­ta­ted. When the crea­tor of the uni­ver­se looks at you, he does not see your mista­kes, but your poten­ti­al. He does not see your past, but your cal­ling. Many peo­p­le strugg­le with self-doubt becau­se they belie­ve that they are not enough. But God’s thoughts are dif­fe­rent. He says: You are wan­ted. You are loved. You are cal­led. What God has spo­ken about us will cer­tain­ly chan­ge our lives.

«So it is with my word that comes from my mouth. It will not return wit­hout fruit, but it will do what I want and ful­fil what I have sent it for» (Isai­ah 55:11 NLB). We can be full of con­fi­dence: His words bring life and healing.

 You are wonderfully made

«I thank you that I am won­derful­ly made; won­derful are your works, and my soul reco­g­ni­s­es them well» (Psalm 139:14 LUT). David speaks a pro­found truth here: Self-accep­tance beg­ins with gra­ti­tu­de. He reco­g­ni­s­es: «I am won­derful­ly made.» We are a mas­ter­pie­ce of God. One day I dis­co­ver­ed what I do when I look at mys­elf nega­tively, when a lot of things about me bother me. When I do that, I accu­se God, then I say to him, your job was bad, you did­n’t do any­thing good. But the word of God says some­thing else. 

How often do we look in the mir­ror and only see what we lack? But God invi­tes us to see with his eyes. You are not an acci­dent. You are not a mista­ke. You are an expres­si­on of divi­ne crea­ti­vi­ty. When you begin to belie­ve that, your thin­king chan­ges. And your thin­king chan­ges your life.

Thoughts shape reality and bring life

«More than any­thing else, guard your heart, for life emana­tes from it» (Pro­verbs 4:23 LUT). The heart – in the bibli­cal sen­se – is the seat of your thoughts, fee­lings and decis­i­ons. What you think about yours­elf influen­ces how you behave, how you form rela­ti­onships and how you deal with challenges.

If you belie­ve that you are wort­hl­ess, you will behave like one. If you belie­ve that you are loved, you will live with cou­ra­ge and hope. That’s why the Bible says: Guard your heart. Pay atten­ti­on to what you think about yours­elf. Becau­se the­se thoughts are like seeds – they grow and bear fruit.

Think the good

«What true what is hono­ura­ble, what is just, what is pure, what is lova­ble, what has a good repu­ta­ti­on – be mindful of this» (Phil­ip­pians 4:8 LUT). Paul gives us here a kind of Thought fil­ter. Not ever­y­thing we think is true. Not ever­y­thing we belie­ve about our­sel­ves comes from God.

That is why it is important to scru­ti­ni­se our thoughts:

  • Is this thought true?
  • Is it con­s­truc­ti­ve?
  • Does it lead me clo­ser to God’s truth?

When you start, Cul­ti­va­te good thoughts about yours­elfyou will noti­ce how your inner cli­ma­te chan­ges. You will beco­me cal­mer, clea­rer and more hopeful.

Science confirms: Thoughts influence health

A stu­dy by the Uni­ver­si­ty of Cali­for­nia, Ber­ke­ley (2018) show­ed that posi­ti­ve Self-per­cep­ti­on direct­ly with bet­ter immu­ne func­tion, lower stress levels and hölife satis­fac­tion is con­nec­ted. Peo­p­le who view them­sel­ves with com­pas­si­on and app­re­cia­ti­on have mea­sura­ble Fewer inflamm­a­to­ry mar­kers in the blood and a Lower sus­cep­ti­bi­li­ty to depres­si­on. This con­firms: What you think about yours­elf not only influen­ces your psy­che – but also your body.

Other rese­arch pro­jects also con­firm that our thoughts have a direct influence on our health. A Cam­bridge stu­dy from 2023 con­firms ear­lier fin­dings that show that nega­ti­ve thoughts can make a signi­fi­cant con­tri­bu­ti­on to trig­ge­ring or main­tai­ning depression.

Reprogramming thoughts – Caroline Leaf

The Chris­ti­an neu­ro­sci­en­tist Dr Caro­li­ne Leaf has spent over 30 years rese­ar­ching the con­nec­tion bet­ween the brain, thoughts and beliefs. She says: «You are not a vic­tim of your bio­lo­gy. You can chan­ge your brain by chan­ging your thin­king.» «You are not a vic­tim of your bio­lo­gy.» You can chan­ge your brain with your thoughts. This means: You can learn, Reco­g­ni­se and replace nega­ti­ve thought pat­terns. You are not at the mer­cy of God – you are empowered. God has given you the abili­ty to renew your mind (Romans 12:2) and ther­eby chan­ge your life. The living Word of God says: «The­r­e­fo­re, do not be gui­ded by the beha­viour and habits of this world, but let God trans­form you into new peo­p­le by chan­ging your way of thin­king» (Romans 12:2 NLB).

Practical steps to good thoughts

1. reco­g­ni­se the lies!
What thoughts about yours­elf are not in line with God’s Word? «I’m not enough.» – «I will never make it.» – «I’m not lova­ble.» The­se thoughts are not from God.

2. replace it with truth
Use Bible ver­ses such as Jere­mi­ah 29:11 or Psalm 139:14 as a dai­ly remin­der: «I am won­derful­ly made.» «God has good thoughts about me.» «I am loved and called.»

3. say it out loud
Words have power. Speak good thoughts about yours­elf every day. Not out of pri­de, but out of faith.

4. sur­round yours­elf with truth
Read the Bible, lis­ten to ser­mons, talk to peo­p­le who remind you of God’s view of you.

Good thoughts about yours­elf is not a super­fi­ci­al opti­mism. It is a spi­ri­tu­al act of rene­wala psy­cho­lo­gi­cal step towards heal­ing and a prac­ti­cal path to a healt­hy life. You are not defi­ned by the mista­kes or opi­ni­ons of others, but through God’s encou­ra­ge­ment! You are not what others say about you. You are not what your past whis­pers to you. You are what God says about you – and that is mar­vell­ous, loved, appoin­ted, high and valuable.

Application

Reco­g­ni­se the lie.
We may have known about them for a long time – but we keep fee­ding them, con­scious­ly or uncon­scious­ly. One prac­ti­cal appli­ca­ti­on could be to redu­ce our con­sump­ti­on of social media – or even do wit­hout it altog­e­ther. After all, we are con­stant­ly con­fron­ted with com­pa­ri­sons, ide­als and dis­tor­ted images that feed fal­se thoughts about ourselves.

Replace it with the truth.
How about memo­ri­sing the ver­se in Psalm 134:19?

Say it – think it out.
Our thoughts are some­ti­mes like a scrat­ched record: they repeat the same nega­ti­ve pat­terns day after day. But we have the choice to break the­se inner loops. A prac­ti­cal appli­ca­ti­on could be to con­scious­ly remem­ber God’s thoughts about us on the way to work.

Sur­round yours­elf with truth.
Lis­tening to a ser­mon on Sun­day is a good start – a moment in which God’s word tou­ch­es our hearts. But truth does­n’t just need to be heard once a week, it needs to be lived and absor­bed every day. A next step could be to lis­ten to a Chris­ti­an radio sta­ti­on – for exam­p­le on the way to work, while coo­king or in quiet moments. In this way, God’s truth beco­mes a con­stant com­pa­n­ion in ever­y­day life – not just on Sun­days, but in the midst of life.

I trust that the Holy Spi­rit speaks to each of us per­so­nal­ly, tou­ch­es us and gui­des us on his path. «Lord, I thank you that you have good thoughts about me. Help me to keep my heart and renew my thoughts. Show me whe­re I have belie­ved lies – and replace them with your truth. I am won­derful­ly made. I am loved. I am yours. Amen.»
