Something wondrous happened to them on that day, which was about 10 days after Jesus ascended to heaven.
This fullness is possible only by being joined to Him, and this can happen only through the Holy Spirit's working in our lives.
The creeds further maintain that Jesus bodily ascended into heaven, where he reigns with God the Father in the unity of the Holy Spirit, and that he will return to judge the living and the dead and grant eternal life to his followers.
His incarnation, earthly ministry, crucifixion and resurrection are often referred to as "the gospel", meaning "good news".
Christian theology is summarized in creeds such as the Apostles' Creed and Nicene Creed.
These professions of faith state that Jesus suffered, died, was buried, descended into hell, and rose from the dead, in order to grant eternal life to those who believe in him and trust in him for the remission of their sins.
