"And Jesus, when he was baptized, went up straightway out of the water: and, lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove, and lighting upon him." (Matthew 3:16)

There are several beautiful symbols of the Holy Spirit in the New Testament. The first is that of the dove, here mentioned in the very first New Testament reference to the Spirit. It was the dove, of course, that first assured Noah that the earth had risen out of the death waters of the great Flood, just as Christ now rose up out of the baptismal waters to receive the dove-like Spirit.

The water itself is also an emblem of the Spirit in its cleansing efficacy and life-sustaining virtue. Jesus said, "Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God" (John 3:5). This could also be translated "born of water, even the Spirit." When He promised "rivers of living water" to those who believed on Him, "this spake he of the Spirit, which they that believe on him should receive" (John 7:38-39).

Then, there is the wind: sometimes a gentle breeze, sometimes a mighty hurricane, and this also symbolizes the Holy Spirit. "The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit" (John 3:8).

John the Baptist said, "I indeed baptize you with water; but one mightier than I cometh. . . . he shall baptize you with the Holy Ghost and with fire" (Luke 3:16). The Holy Spirit is God; "our God is a consuming fire" (Hebrews 12:29). The Spirit of God is a gentle dove and living water; He is the blowing wind, and a consuming fire; He is our "Comforter" (John 14:26), "the Spirit of truth" (John 14:17), and "the Spirit of life in Christ Jesus" (Romans 8:2).
