This episode expounds on the testimony of the personhood of the Holy Spirit from the New Testament. While Jews affirm the deity of the Holy Spirit, they deny that the Spirit is a distinct person of the godhead, mostly claiming that references to the Holy Spirit are simply manifestations of God. But this "manifestation" rubric doesn't adequately do justice to the clear personal qualities attributed to the Holy Spirit, who can be lied to (Acts 5:3), tested (Acts 5:9), resisted (Acts 7:51), insulted (Hebrews 10:29), grieved (Ephesians 4:30), and blasphemed (Matthew 12:32). Rejection of the distinct personhood of the Holy Spirit therefore means that Jews do not believe in the same God as Christians.
The Trinity Revealed in the Old Testament
In addition to rehashing several Old Testament passages on the personhood of the Holy Spirit, this episode cites three passages from Isaiah where every member of the godhead is present in the same verse. Isaiah 42:1 declares "I [God the Father] have put my Spirit[God the Holy Spirit] upon Him[God the Son]." A godhead without distinctions makes no sense, and Isaiah 48:16 also bears this out, "And the Lord God has sent Me, and His Spirit." The "Me" refers to the Messiah, the suffering Servant, who together with the Holy Spirit, are sent by God the Father. Finally, in a passage quoted by Christ Himself (Isaiah 61:1) (Luke 4:18-19), Isaiah declares, "The Spirit of the Lord God is upon me.." All three persons of the Trinity are present, and the Christian doctrine of 3 persons comprising one God finds its roots solidly in the Old Testament.
“Obedience: Tasting and Seeing that the Lord is Good
This episode addresses a common concern among Christians over their lack of spiritual growth or fulfillment. The answer may lie in a holistic picture of salvation, in which obedience and doing God's will is center-stage. Christ's said that "his food was to do the will" of the Father. (John 4:34) Doing God's will is nourishing to spiritual growth and provides true fulfillment, even motivating us for more service to God. The episode paints the sharp contrast between being filled up with the fulness of God in singular devotion to Christ and spiritual lethargy characterized by spiritual insensitivity and preoccupation with the cares of this world. Understanding this dynamic helps us make adjustments that foster spiritual growth and promote higher degrees of the beatific vision.
