Steve Walton states that Jesus’ ascension “expresses the Christian conviction that Jesus now reigns over the universe” (59) and “The ascension of Jesus … provides the apostles with a visual demonstration of the truth of Jesus’ exalted status” (60).
In addition to these summary-type statements, he provides 7 significant theological implications of the ascension.
(1) The ascension implies that Jesus now reigns alongside God in heaven, and thus it is appropriate to call him *“Lord” as well as “Messiah” (Acts 2:36). The (singular) cloud (Acts 1:9) echoes the one in Luke 21:27 on which the *Son of Man comes to God (cf. Dan 7:13), clearly placing Jesus alongside Israel’s God. Thus Jesus, still human, is to be *worshiped (Lk 24:52) alongside Yahweh, and the portrait of Israel’s God expands (Johnson). Psalm 110 (esp. Ps 110:1, 4) was a key biblical passage that was interpreted (following Jesus’ own lead [Mk 12:35–37]) concerning Jesus, who is thus to be understood as having been enthroned at God’s right hand as coruler (e.g., Rom 8:34; Heb 10:12–13).
(2) The ascension presages Jesus’ return to earth from heaven (Acts 1:11; cf. Heb 9:28). That return will be the time of cosmic renewal and restoration promised in Scripture (Acts 3:20–21) and of *judgment (Acts 17:31). The cloud—a key marker of Jesus’ departure (Acts 1:9)—became an emblem of Jesus’ return in early Christian writing (e.g., 1 Thess 4:17; Rev 1:7; 14:14–16). Paul picks up Psalm 110:1 as testimony that the time will come when God will place Jesus’ enemies under his feet (1 Cor 15:25–26). The ascension is “the advance notice of the end” (Robinson, cited in Zwiep, 196).
