Everyone – everyone who believes in Jesus is called to be His ambassador. An Ambassador of Christ. That involves a change of heart, it involves a change in our actions and it involves – well, going. Ambassadors don’t stay, they go. That’s why being Christ’s Ambassadors ain’t easy sometimes.

 

Christ on the Inside

Now, one of the things that you and I know is that we are what we eat. If what I do is I pig out on chocolates – man, I love chocolate, but we know that too much of it is bad for us; and fatty foods and sweet, sugary drinks and lots of cakes and sweets, all that stuff – if I pig out on that then who I am on the inside is going to change. I’m going to put on weight, my emotions will take a downswing, because that’s what happens with too much sugar, I’ll become lethargic and tired and I won’t be able to cope. My heart will have to work so much harder to get blood around the larger body and my coronary arteries will get all clogged up, my blood sugar will go up ... and on and on the list goes.

The impact is that I have less of a life to live now because I’m always tired, not feeling well and my life expectancy will be cut short. On the other hand, if I get a great mix of healthy cereals and grains and those brightly coloured vegetables and lean meat and all that stuff, which actually tastes pretty fantastic, the complete opposite will happen. What happens on the inside has a huge impact on what happens on the outside.

Who we are on the inside – whether it be physically or emotionally or spiritually - has a huge impact on who we are on the outside. And the upshot of all that is that we simply can’t be one thing on the inside and try to be something else on the outside – it just doesn’t work.

Last week, again this week on the programme and indeed, over the next couple of weeks we are having a bit of a chat about living our lives here on this earth as ambassadors for Christ, because that is what anyone who believes in Jesus is called to be. We are citizens of heaven, not of this earth and as Paul, the Apostle writes, in Second Corinthians chapter 5, verse 20:

We are ambassadors for Christ; since God is making his appeal through us, we entreat you on behalf of Christ, to be reconciled to God.

As I said, you just can’t be one thing on the inside and then pretend to be another thing on the outside. You can’t be Swedish on the inside and pretend to be the Indian ambassador on the outside. We can’t be the devil on the inside and pretend to be an angel of light on the outside. Well, I suppose we can for a while but I suspect it’s incredibly hard work, carrying on a deception like that and it doesn’t take long for who we are to make its way to the outside.

Jesus Himself said – Matthew chapter 15, verse 19:

For out of the heart come evil intentions, murder, adultery, fornication, theft, false witness and slander.

So, if we are going to be ambassadors of Christ, then we first have to be citizens of heaven on the inside, just as the Indian ambassador has to be Indian and not Swedish on the inside. Interesting how God talked about this through His prophet Ezekiel, to His people. He talked to them about what was going on in their hearts. Have a listen – Ezekiel chapter 18, verse 31:

“Cast away from you all the transgressions that you have committed against me and get yourselves,” listen to this, “a new heart and a new spirit. Why will you die, O house of Israel?"

A new heart! I think we know what God means but that’s not much of an expression that we would use today. But the expression that we would use is "a change of heart". You and I know what that means: unless something happens deep inside our hearts – on the inside - we can’t change on the outside. But you know there have been issues, transgressions, sins in my life that, try as I might, I couldn’t change my heart by myself. I’m guessing you have had that experience too – we all have!

And that’s why God made this promise too, through His prophet Ezekiel, to His people – Ezekiel chapter 36, verse 26:

A new heart I will give you, a new spirit I will put within you and I will remove from your body the heart of stone and give you a heart of flesh.

In fact, perhaps what you want to be is an ambassador of Christ but there’s something right now going on in your heart; something you would love to change but you can’t for yourself that you need God to do for you. So why don’t we pray about that right now:

Father God,
this Word of yours, You are putting Your finger right on one of the deepest problems in my life. You and I both know what it is and You know that I have struggled to change my heart - I’ve tried my hardest, but I just can’t. And so I come to You in faith and pray for Your will – Ezekiel chapter 36, verse 26 – for a new heart – a change of heart. Take out the heart of stone, O God, and replace it with a heart of flesh. Take out of me any spirit that is causing me to sin and fill me with Your Spirit. I come to You in faith. I believe that what I have asked You, You will give me because I am asking You in the name of Jesus. Amen.

Now, I encourage you, if you have prayed that prayer will me, to believe, simply to believe, that God will give you the good thing that you have asked Him for and He will. That’s what He says He will do and He never, ever, ever fails on His Word – ever!

When the Apostle Paul was sharing the Good News about Jesus with the folk in Athens, he quoted a poem about a Greek god and applied it to Jesus. This is what he said – Acts chapter 17, verse 28:

For in him we live and move and have our being.

You know, for me that says it all! It’s about being totally immersed in Christ; about being drenched in Jesus – that’s actually the literal meaning of the word "baptised or baptism". The original Greek word was "baptidso". So when a boat was lost in a storm and it went under and it sank, it was said to have been "baptidso"d. When a fabric was dyed a new colour and it was plunged into the dye and completely drenched and it came out a new colour, it was said to have been "baptidso"d.

That’s exactly what the Apostle Paul writes to his friends in Rome. Romans chapter 6, verses 3 and 4:

Don’t you know that all of us who have been baptised into Christ were baptised into his death? Therefore, we have been buried with him by baptism into death so that just as Christ was raised again from the dead by the glory of the Father, so we too might walk in newness of life.

It means death to the old life and the living of a new life; literally, to be "born again" – a whole new heart and filled with a new spirit; the Spirit of God this time; the Holy Spirit. It means that goodness replaces evil – not so much because we work hard at it but because God’s given us a change of heart and now what happens is we actually want to honour God; we want to live a life that brings glory to Him – and that’s the new life.

We are going to talk more about that next. It’s the new life that wins people over to Christ. It’s the new life that shines like a light and brings flavour to people’s lives like salt. But just as a well that is dry can’t bring forth water, so a life that is empty of Christ; His very Spirit; His presence within us, so a life like that can’t be an ambassador of Christ.

If there are things that you have been struggling with on the inside; things that are holding you back from taking up your commission as Christ’s ambassador in your little petunia patch, then here’s what I encourage you to do – get with God, get in prayer, open His Word, ask Him to fill you to overflowing with His Holy Spirit. Ask Him again and again and again to give you a new heart. And just as we prayed before; just as I said before, He surely will – because He wants to – because when we bear much fruit in our lives it brings Him great glory. A new heart; a change of heart; filled with a new spirit, His Spirit.

 

Christ on the Outside

So let me ask you a question: if you are someone who believes in Jesus and you drive a car, do you have a Jesus bumper sticker or one of those fish stickers on your bumper bar? Maybe ... maybe not! I mean, even if you don’t, that’s okay, I don’t either, but if you had to put one on your car, let me ask you, does your behaviour on the road as a driver match up to what the sticker advertises? I mean, are you a courteous driver who obeys all the road rules or do you break the speed limit and honk your horn at people and yell at them from the inside of your car?

I guess if you’re the former it would be okay to have a fish sticker or a Jesus sticker on your car because your behaviour is a good advertisement for God - in effect, because what you advertise on the sticker and how you behave match up, it works. On the other hand though, can you imagine a rude, impatient driver, who’s constantly breaking the road rules, identifying themselves as a Christian, using some sticker they put on their car. It’s not a very good ad for God, is it?

It turns out that who we say we are; who we hold ourselves out to be and who we actually are in what we say and what we do – if those two don’t match up – well, there’s a name for that: we call those people "hypocrites". We have been talking about living our lives as ambassadors of Christ – “for we are ambassadors for Christ since God is making his appeal through us.” 2nd Corinthians cha
