What does the Bible say about the unction from Christ?

The term 'unction' as mentioned in 1 John 2:20 refers to an anointing from the Holy One, which is Christ. This anointing implies that believers receive the power of a resurrected life that is rooted in Christ Himself. Since we are born spiritually dead due to the fall in Adam, the Holy Spirit brings us under the gospel message and resurrects us spiritually, enabling us to have faith in Christ. This unction thus serves as both a gift of the new birth and a sustaining power that keeps believers in their faith throughout their life.
