J. I. Packer compares the Holy Spirit to a floodlight in front of a house. The floodlight exists not to draw attention to itself but to illuminate the house. In the same way, the Holy Spirit’s primary work is to shine light on Jesus and glorify God the Father. 18 This is why Dale Bruner calls him “the shy member of the trinity.” 19 But when this primary focus is lost, union with Christ will be lost as well.
