His ascension was a fulfillment of what He prophesied; Jesus foretold of His ascension into heaven (Jo. 6:62; 14:2; 12; 16:5; 10; 28; 20:17). After Jesus resurrected, He spoke with a wide variety of people before ascending into heaven. First Jesus appeared to Mary (Jo. 20:11-28), then to both Mary and Mary Magdalene (Matt. 28:9-10), then to Cleopas and another man on the way to Emmaus (Luke 24:13-22), then to Peter (Luke 24:34; 1Cor. 15:5). Second, Jesus appeared to Thomas and the disciple (Jo. 20:26; 31; 1Cor. 15:5), then again to the disciples (Jo. 21:1-5), then again to the disciples (Matt. 28:16-20), then to over 500 followers at the same time (1Cor. 15:6), then to James (7), then to the apostles (8).
After resurrecting, Jesus came to be with His disciples (Jo. 20:17; Mark 16:19), gave them final instructions (Matt 28:16-20), blessed them (Luke 24:50), and while blessing them He ascended into heaven (Acts 1:9; Jo. 20:17; Luke 24:51) to sit at the right hand of the Father (Acts 2:33; Jo. 17:5; Mark 16:19) with authority over all (1Pet. 3:22). Jesus descended far below, and ascended high above (through heaven [Heb. 4:14]) in order to fill all places with the glory of God (Acts 9:3; 5). All that was done was orchestrated by God the Father (Eph. 1:20; 1Tim. 3:16; Heb. 1:3; 4:14; 9:24; 1Pet. 2:23).
