The union between the Father and the Son is such a live concrete thing that this union itself is also a Person. I know this is almost inconceivable, but look at it thus. You know that among human beings, when they get together in a family, or a club, or trade union, people talk about the ‘spirit’ of that family, or club, or trade union. They talk about its ‘spirit’ because the individual members, when they are together, do really develop particular ways of talking and behaving which they would not have if they were apart. It is as if a sort of communal personality came into existence. Of course, it is not a real person: it is only rather like a person. But that is just one of the differences between God and us. What grows out of the joint life of the Father and the Son is a real Person, is in fact the Third of the three Persons who are God.
This third Person is called, in technical language, the Holy Ghost or the ‘Spirit’ of God. Do not be worried or surprised if you find it (or Him) rather vaguer or more shadowy in your mind than the other two. I think there is a reason why that must be so. In the Christian life you are not usually looking at Him. He is always acting through you. If you think of the Father as something ‘out there’, in front of you, and of the Son as someone standing by your side, helping you to pray, trying to turn you into another son, then you have to think of the third Person as something inside you, or behind you. Perhaps some people might find it easier to begin with the third Person and work backwards. God is love, and that love is, from all eternity, a love going on between the Father and the Son.
C.S. Lewis Mere Christianity
Today1 we are celebrating the feast of Pentecost. A regular feature of Pentecost tends to be a talk based on the Acts reading, Joel’s prophecy and tongues of fire.
And so, I am going to talk about our Gospel reading from John; where Jesus us reassuring the disciples that this is not the end of their relationship with Him. They would not be abandoned or left helpless as Jesus was going to the Father to send the Holy Spirit to be with them … and us.
Jesus said, “Believe in God, believe also in me”. This is a fundamental relationship of trust.
Jesus graciously left the gift of His peace. He said, “Peace I leave with you, my peace I give you”.
True peace is not derived from circumstances, people or things; true peace is derived from Jesus. His peace is peculiarly His to give as He purchased it with His precious blood. Jesus was the substitution for a perishing world. Jesus was commissioned to bring peace to mankind.
Jesus is The Way!
To know Jesus is to know both the way and the destination, which is communion with the Father. In order to complete His atonement for our sin Jesus had to leave and return to the Father. But Jesus leaving is linked to the role of the Holy Spirit – the Helper Jesus had referred to previously.
Jesus was returning to the Father to prepare a place for us.
Jesus is The Way, The Truth and The Life!
Jesus in His life, ministry, actions, everything that He did showed us GOd. Now it is time for Him to return to the Father, He promises the companionship of the Holy Spirit so that the disciples, and us, will be able to continue in Jesus’s way of doing things.
We can only understand and know the Holy Spirit if we know and understand the unity of the other two Persons of the Trinity – the Father and the Son. The Holy Spirit is often thought of as this bond of love between Father and Son.
Jesus describes the Holy Spirit a “another Advocate to be with you forever”. The love of the Father and His desire to be reconciled with His creation is what led to Jesus’s incarnation in the first place and is the reason for God sending the Spirit to us; God is our Advocate – the one who is by our side, no matter what, no matter which persona of the Trinity (Father, Son and Holy Spirit) it is.
The Holy Spirit is the Spirit of Truth and will be in us – not just by our side.
This Spirit is in us, united with us, the way the Father and the Son are united in each other. This bond with the Spirit enables the Spirit to be our guide in life just as Jesus did the will of God His Father.
The Holy Spirit is our guiding light – our tongue of fire – if the Spirit dwells in us.
But because it is the guiding light for those in whom it dwells, the world cannot receive the Spirit. The world refuses to see the Spirit of Truth alongside them, tapping them on the shoulder with a call to repentance. They do not want to return to being God’s original and beautiful masterpiece. They only see their own gain and not the loveliness of God.
If we can see it in Jesus, if we can see that the Holy Spirit is by our side and in our lives. If we can recognise the real truth and call upon our God to help us do the things He would have us do, then we will know the presence of God within us and His guiding light before us – our tongue of Spirit fire.
