Resurrection
is,

Being raised from the dead.
Resurrection can mean being raised from physical death, or it can mean being raised from spiritual death unto spiritual life.
Jesus promises us both.
(See more at  
'Born Again'.)
  
...That I may know Him,
and the power of His resurrection, and
the fellowship of His sufferings, being made conformable unto His death; If  by any means I might attain unto the resurrection of the dead.
Not as though I had already attained, either were already perfect: but I follow after, if that I may apprehend that for which also
I am apprehended of
Christ Jesus.

Phillipians 
3:10-12   
Know ye not, that so many of us as were
baptized into Jesus Christ were baptized into
His death? Therefore we are buried with Him
by baptism into death: That like as Christ was
raised up from the dead by the glory of the Father,
even so we also should walk in the newness of life.
For if we have been planted together in the
likeness of His death, we shall be
also in the likeness of His
resurrection...

Romans   
6:3-5   
There was a darkness over all the earth;
and, as Jesus gave up the Ghost, the earth shook, the rocks were broken, and
in the temple, the veil of cloth  which divided the Holy of Holies from the Holy Place was torn in two, signifying that we would no longer need a human priest to go to God to offer sacrifices and pray for us. Through Christ, the Perfect Lamb and the highest priest of all, who sacrificed Himself for us, we would now be allowed
to enter into the very presence of God in our own hearts,
as we are also 'seated in heavenly places'.  Three
days later, God raised Jesus from the dead.  Many
bodies of the saints that slept (had died) were
raised from their graves,
as well, and
walked and were seen in the city.
Matthew 27-28   
Mark 15-16  
Luke 23-24   
John 19-20     
On the day of Christ's return,
all those who are 'dead in Christ' will be
raised from the dead, (the'Resurrection of the Dead') and then those in Christ who are "alive and remain shall be caught up together with them in the clouds, to meet the Lord in
the air: and so shall we ever be
with the Lord".
