Why is the Holy Spirit symbolised by oil?

Question 4150.

The Spirit symbolised by oil is one of the oldest pictures in the Bible, and it carries a weight that is easy to miss if we only think of oil as something for cooking or for soothing dry skin. In the ancient world oil was the substance of consecration. When something was set apart for God, it was anointed.

To ask why the Spirit symbolised by oil should appear so often is really to ask what anointing meant, and what it pointed forward to. The answer takes us through the kings, the priests and the prophets of Israel, and it lands at the feet of the one whose very title means the Anointed One.

The Spirit symbolised by oil and the act of anointing

Throughout the Old Testament, when a man was appointed to an office under God, oil was poured over his head. Samuel anointed Saul, and then David. The high priest was consecrated with oil. The pattern is so consistent that the act of anointing became shorthand for divine appointment and divine enabling. The oil itself did nothing magical, but it signified that the Spirit of God was now resting on this person for the task ahead.

That is the heart of why the Spirit symbolised by oil makes such sense. Anointing was the visible sign of an invisible reality. When the oil ran down, everyone could see that this man was set apart, and the hope was that the Spirit they could not see had come upon him for the work he could not do alone.

It is worth pausing on how ordinary the substance was. Olive oil was the stuff of daily life in Israel, used for cooking, for lamps, for soothing the skin. God did not reach for something rare and exotic to picture his Spirit. He took the common oil from the kitchen and the lamp and made it the sign of consecration. There is grace in that. The Spirit comes not to the elite of the earth but to ordinary people set apart for an extraordinary God.

The Spirit rushing upon the anointed king

Watch what happens when Samuel anoints David. ‘Then Samuel took the horn of oil and anointed him in the midst of his brothers. And the Spirit of the LORD rushed upon David from that day forward’ (1 Samuel 16:13). The oil is poured, and the Spirit comes. The sign and the substance arrive together. The text does not let us separate the anointing with oil from the coming of the Spirit, because the one was always meant to point at the other.

This is why the Spirit symbolised by oil speaks of empowerment for service. David was not anointed so that he could feel special. He was anointed so that he could shepherd the people of God and fight their battles. The oil meant equipping, and the Spirit gave the strength the role demanded.

The same pattern runs through the prophets and the priests. The prophet was anointed to speak God’s word, the priest to stand between God and the people, the king to rule under God. In every case the oil pointed to a task that no one could carry in his own strength, and to a Spirit who supplied what the task required. Office without enabling would have been a cruel burden. The anointing promised that the God who appoints also equips.

The Anointed One

All of this gathers to a point in our Lord. The word Messiah means Anointed One, and so does the Greek word Christ. When Jesus stood up in the synagogue at Nazareth he read from Isaiah, ‘The Spirit of the Lord is upon me, because he has anointed me to proclaim good news to the poor’ (Luke 4:18). Here the anointing is no longer oil poured from a horn. It is the Spirit himself, resting on the Son without measure.

Peter later summarised the whole ministry of Jesus in these terms, telling Cornelius how ‘God anointed Jesus of Nazareth with the Holy Spirit and with power’ (Acts 10:38). The Spirit symbolised by oil throughout the old covenant finds its true meaning in the Christ on whom the Spirit came in fullness. Every horn of oil in the Old Testament was a signpost pointing here.

And notice the manner of his anointing. At his baptism the Spirit descended on him visibly, and the Father spoke from heaven. There was no horn of oil that day, because the substance had given way to the reality it had always pictured. The kings and priests received a little oil on the head. The Son received the Spirit without measure, and out of his fullness we have all received grace upon grace.

Anointed in him

What is wonderful is that the New Testament then turns this picture toward ordinary believers. Paul writes that ‘it is God who establishes us with you in Christ, and has anointed us, and who has also put his seal on us and given us his Spirit in our hearts as a guarantee’ (2 Corinthians 1:21 to 22). The anointing has come to us. We share, in him, in the reality that the kings and priests only tasted.

John says much the same when he reminds his readers that ‘you have been anointed by the Holy One’ (1 John 2:20). This is closely tied to the sealing of the Spirit, which I unpack in my answer on the sealing of the Holy Spirit. The Spirit symbolised by oil is no longer reserved for an elite. He is given to every believer at conversion.

I want to be careful here, because some take this language of anointing and build a special class of super-anointed leaders who can dispense the Spirit to lesser Christians by a touch. Scripture knows nothing of it. John says you, all of you, have been anointed by the Holy One. The anointing is the common possession of every believer, not the trade secret of a gifted few, and any teaching that makes it otherwise has wandered from the plain sense of the text.

Oil for the lamps

There is a second strand to the oil picture, and it has to do with light. The lamps in the tabernacle and the temple burned olive oil, and they were never to go out. In Zechariah’s vision the prophet sees a lampstand fed by two olive trees, and the meaning given is ‘Not by might, nor by power, but by my Spirit, says the LORD of hosts’ (Zechariah 4:6). The oil keeps the light burning, and the oil is the Spirit.

I find that a searching image. A lamp with no oil is just a cold ornament. A Christian trying to shine without the supply of the Spirit will gutter and smoke and finally go dark. The Spirit symbolised by oil is the Spirit who keeps the flame of witness and worship alive in us, and the supply has to be constant. This is why the distinction between being indwelt once and being filled continually matters so much, which I cover in the born, baptised, filled and sealed distinctions.

The wise virgins in our Lord’s parable were the ones who took oil for their lamps, and the foolish were those whose lamps went out for want of it. I do not press every detail of a parable, but the warning is plain enough. A profession of faith that is not fed by the ongoing supply of the Spirit will not last the night. The lamps that are still burning when the Bridegroom comes are the lamps that have kept drawing on the oil.

Oil for gladness and healing

Oil in Scripture also speaks of joy and of care. The psalmist praises God for ‘oil to make his face shine’ (Psalm 104:15), and the wounded man in the parable has oil poured into his injuries. So the Spirit symbolised by oil is not only about office and power. There is gladness in it, and there is tenderness. The Spirit anoints us for service, but he also gladdens the heart and binds up wounds.

Hold these strands together and you have a rounded picture. Oil consecrates, oil empowers, oil gives light, oil brings joy and oil heals. Each of these is a true word about the Spirit who has been poured out on the people of God.

Let none of this feel distant. The Spirit symbolised by oil is given to gladden the hearts of ordinary believers today, not only to equip prophets and kings long ago, and a Christian who walks closely with him will know that quiet anointing of joy even in the hard seasons.

So, now what?

If you belong to Jesus, then you are an anointed person. Let that settle on you for a moment. The same Spirit who rushed upon David and rested without measure on the Anointed One has been given to you. You are not waiting at the door hoping for an anointing that may never come. In Christ it is already yours.

So the question is not whether you are anointed, but whether your lamp is well supplied. Are you drawing on the oil daily, in the Word and in prayer and in glad obedience? A lamp burns brightest when it is full. Why not come back to the supply today and let the Spirit gladden a heart that has been running on fumes?

But you have been anointed by the Holy One, and you all have knowledge. (1 John 2:20, ESV)
