The Holy Spirit is called the “oil of gladness” in Heb. i. 9, “Thou hast loved righteousness, and hated iniquity; therefore God, even thy God, hath anointed thee with the _oil of gladness_ above thy fellows.” Some one may ask what reason have we for supposing that “the oil of gladness” in this passage is a name of the Holy Spirit. The answer is found in a comparison of Heb. i. 9, with Acts x. 38 and Luke iv. 18. In Acts x. 38 we read “how God anointed Jesus of Nazareth with the Holy Ghost and with power,” and in Luke iv. 18, Jesus Himself is recorded as saying, “_The Spirit of the Lord is upon_ Me, because He hath _anointed_ Me to preach the Gospel to the poor,” etc. In both of these passages, we are told it was _the Holy Spirit with which Jesus was anointed_ and as in the passage in Hebrews we are told that _it was with the oil of gladness that He was anointed_; so, of course, the only possible conclusion is that the oil of gladness means the Holy Spirit. What a beautiful and suggestive name it is for Him whose fruit is, first, “love” then “joy” (Gal. v. 22). The Holy Spirit becomes a source of boundless joy to those who receive Him; He so fills and satisfies the soul, that the soul who receives Him does not thirst forever (John iv. 14). No matter how great the afflictions with which the believer receives the Word, still he will have “_the joy of the Holy Ghost_” (1 Thess. i. 6). On the Day of Pentecost, when the disciples were baptized with the Holy Spirit, they were so filled with ecstatic joy that others looking on them thought they were intoxicated. They said, “These men are full of new wine.” And Paul draws a comparison between abnormal intoxication that comes through excess of wine and the wholesome exhilaration from which there is no reaction that comes through being filled with the Spirit (Eph. v. 18-20). When God anoints one with the Holy Spirit, it is as if He broke a precious alabaster box of oil of gladness above their heads until it ran down to the hem of their garments and the whole person was suffused with joy unspeakable and full of glory.
