Why The Ascension?

God raised Jesus from the grave and exalted Him to His right hand in heaven (Ephesians 1:20). Yet for 40 days Jesus made many bodily appearances to His disciples. But the 40th day was different. With His disciples looking on, He slowly ascended into the sky until a cloud hid Him from view (Acts 1:9).

Why didn’t Jesus continue His visible appearances on earth?
