Anointing oil is a metaphor for the Spirit of God. “Now it is God who makes both us and you stand firm in Christ. He anointed us, set his seal of ownership on us, and put his Spirit in our hearts…” (2 Corinthians 1:21-22 NIV). God poured out upon you the power-providing, heart-healing oil of the Holy Spirit.
The verb pour deserves to be highlighted. God does not distribute the Spirit with an eyedropper or a tablespoon. He douses us with himself. Do you understand what happened on the day of your conversion? Yes, grace covered you. Yes, the tent of God’s sovereignty was stretched over you. Yes, the pathway to heaven was laid out before you. And yes, you were anointed by the Holy Spirit. You have been consecrated for a holy work.
