Three Days

Acts 10:45 (ESV)

And the believers from among the circumcised who had come with Peter were amazed, because the gift of the Holy Spirit was poured out even on the Gentiles.

Day 1, Cornelius sees an angel of God at the same time of day when the temple curtains are torn at the time of day when Jesus died on the cross. 

Day 2, Peter sees the heavens opened and is shown that the Lord has made all things clean at the time of day when Jesus was nailed to the cross. 

Day 3, the Gentiles receive the Holy Spirit and the living temple of God comes into view. 

Jesus said He would raise the new and living temple in three days, and so it was.
