After Jesus rose from the dead, He “presented Himself alive” (Acts 1:3) to the women near the tomb (Matthew 28:9-10), to His disciples (Luke 24:36-43), and to more than 500 others (1 Corinthians 15:6). In the days following His resurrection, Jesus taught His disciples about the kingdom of God (Acts 1:3).
Forty days after the resurrection, Jesus and His disciples went to Mount Olivet, near Jerusalem. There, Jesus promised His followers that they would soon receive the Holy Spirit, and He instructed them to remain in Jerusalem until the Spirit had come. Then Jesus blessed them, and as He gave the blessing, He began to ascend into heaven. The account of Jesus’ ascension is found in Luke 24:50-51 and Acts 1:9-11.
It is plain from Scripture that Jesus’ ascension was a literal, bodily return to heaven. He rose from the ground gradually and visibly, observed by many intent onlookers. As the disciples strained to catch a last glimpse of Jesus, a cloud hid Him from their view, and two angels appeared and promised Christ’s return “in just the same way that you have watched Him go” (Acts 1:11).
