Why is the Holy Spirit symbolised by oil?

Question 4150

The picture of the Spirit as oil runs quietly through the whole Bible, from the anointing of priests and kings in the Old Testament to the believer’s anointing that John speaks of in his first letter. When Scripture presents the Spirit as oil it draws on the ancient practice of anointing, the pouring out of oil to set a person apart for God and to equip them for the work He has given.

Oil takes its place among the great symbols of the Spirit, alongside the dove, the fire and the wind. Each adds its own colour. The Spirit as oil speaks of consecration, of equipping for service and of the light and gladness that His presence brings, and it leads us straight to the title we give the Lord Jesus, the Anointed One.

Anointing oil and the setting apart of persons

Under the law, oil was poured on those whom God was calling into special service. Aaron and his sons were anointed for the priesthood (Exodus 29:7; Leviticus 8:12). Prophets were anointed (1 Kings 19:16) and kings were set on the throne by the pouring of oil, as Samuel anointed first Saul and then David (1 Samuel 10:1; 16:13). The Spirit as oil stands behind every one of these scenes, for the oil was the outward sign of an inward reality, the coming of the Spirit of the Lord upon the one anointed.

This is made plain in David’s case. Samuel anointed him with oil, and the very next line says that the Spirit of the Lord rushed upon David from that day forward (1 Samuel 16:13). The oil and the Spirit move together. So the Spirit as oil tells us that those whom God calls He also equips, and that the equipping is the gift of His own Spirit rather than any natural talent of the one called.

The recipe for the holy anointing oil itself, given to Moses, underlines how set apart this was. It was compounded of choice spices and olive oil after the art of the perfumer, and God forbade anyone to make a copy of it for common use (Exodus 30:22 to 33). The oil was holy because it pointed to a holy reality, the Spirit of God Himself. To imitate it for ordinary ends was to trifle with what God had reserved for His own purposes, a warning that still stands against every attempt to counterfeit the work of the Spirit as oil by mere technique or showmanship.

The Spirit as oil and the Anointed One

The whole pattern points beyond priests and kings to one greater. The Hebrew mashach, to anoint, gives us the word Messiah, and its Greek equivalent chrio gives us Christ. Both titles mean the Anointed One. When the Lord Jesus stood in the synagogue at Nazareth and read from Isaiah, He claimed exactly this. The Spirit of the Lord is upon me, He said, because He has anointed me to proclaim good news (Luke 4:18; Isaiah 61:1). The Spirit as oil rested on Jesus without measure, marking Him as the true Prophet, Priest and King.

This anointing was not a private privilege but the source of His whole ministry of teaching, healing and deliverance, as Peter later summed it up when he said that God anointed Jesus of Nazareth with the Holy Spirit and with power (Acts 10:38). The Spirit as oil that flowed down on Aaron’s head finds its fulfilment in the One on whom the Spirit came to remain, a truth we open up further in our answer on the Spirit in the life of Jesus.

The anointing that every believer shares

What was once reserved for prophets, priests and kings now belongs to all who are in the Lord Jesus. John tells ordinary believers, you have been anointed by the Holy One, and you all have knowledge, and again, the anointing that you received from him abides in you (1 John 2:20, 27). The Spirit as oil is no longer poured on a chosen few but given to every member of the body, so that the whole church is a kingdom of priests.

This anointing teaches and guards us. John’s point is that the indwelling Spirit, the Spirit as oil within, keeps the believer from being deceived by false teachers. The same Spirit who set apart the kings of Israel now sets apart the humblest believer for God and equips them for their share in His service. This is bound up with the sealing of the Spirit, God’s own mark of ownership on those who are His.

We should be careful not to misread John here, as some have done, to mean that a believer who has the Spirit as oil needs no teachers at all. John is not dismissing the ordinary ministry of the word, which God has given to His church. He is assuring frightened believers that they already possess the One who is able to keep them in the truth, so that they need not be swept away by the smooth talk of those who deny the Lord Jesus. The anointing does not replace sound teaching but enables the believer to recognise and hold to it.

Oil that heals and restores

Oil in the ancient world was also medicine. The good Samaritan poured oil and wine on the wounds of the beaten traveller and bound them up (Luke 10:34), and James told the sick to call for the elders to pray over them, anointing them with oil in the name of the Lord (James 5:14). Behind the outward oil stands the gentle, restoring ministry of the Spirit as oil, who pours Himself into broken places and brings healing that no human hand can give.

This tells us something about the manner of the Spirit’s work. Oil does not force or break. It seeps in, softens and soothes. The Spirit as oil works that way in a hardened conscience and a bruised heart, patient and penetrating, loosening what sin has stiffened. The believer who feels worn down by failure or sorrow is invited to come for that anointing, for the Spirit delights to restore the people of God rather than to crush them.

It is worth adding that this restoring oil is never given for the believer’s comfort alone. The one anointed to be healed is anointed to serve, just as the kings of Israel were oiled not for luxury but for a charge. The Spirit as oil pours in that we might be made whole, and pours out through us that others might be helped.

Oil for light and for gladness

Oil did more than consecrate. It fed the lamps of the tabernacle so that the light never went out (Exodus 27:20, 21), and it was used to anoint the head as a sign of joy and welcome (Psalm 23:5; 45:7). The Spirit as oil carries these notes too. He is the One who gives light to understand the Scriptures and who pours the oil of gladness that lifts the downcast heart. Where the Spirit is honoured, there is both clearer sight and deeper joy.

The parable of the ten virgins turns on this very picture. The wise took oil for their lamps and the foolish did not, and when the bridegroom came only those with oil were ready (Matthew 25:1 to 13). Whatever else the parable teaches, it warns that an outward profession without the inward reality of the Spirit as oil is a lamp that will fail at the worst moment. The genuine believer carries the Spirit within, and that supply does not run dry.

There is a sweetness to this last note that should not be missed. The God who comes to us in the refining fire and the unstoppable wind also comes as oil, soothing, gladdening and lighting our way. The Spirit as oil reminds us that the indwelling of God is not a burden to be borne but a kindness to be enjoyed, and that the anointed life, for all its calling and cost, is finally a glad one.

So, now what?

Remember that if you belong to the Lord Jesus you are an anointed person. The Spirit as oil rests on you, not to make you proud but to equip you for the place and work God has appointed. Whatever your calling, do it as one set apart by God, depending on His Spirit rather than your own resources.

Keep the lamp supplied. Lean on the anointing that teaches you, test every voice against the Scriptures the Spirit Himself inspired, and ask Him for the oil of gladness when your heart grows heavy. The God who anointed prophets, priests and kings has poured His Spirit on you, and that is a dignity worth living up to.

Let it also shape how you think of your fellow believers. If the Spirit as oil has been poured on the whole church and not on a privileged few, then there is no room for a Christianity of spectators watching a gifted minority perform. Every member of the body is anointed and equipped for some share in the work, and the humblest service offered in dependence on the Spirit is honoured by God. Look around at the people of God and see anointed ones, called and equipped just as you are.
