A
Disciple
is,

A student; a learner;
a pupil.
Also, a follower.
The followers of the doctrines of Christ
were called His disciples, just as all
Christians are called His disciples
even today, as they follow
after Him and learn
and receive His 
teachings.  
And the angel answered and said unto
the woman, Don't be afraid:
for I know that you seek Jesus who was crucified.  He is not here, for He is risen, as He said. Come, see the place where the Lord did lay. And go quickly, and tell
His disciples that He is risen
from the dead... 
Matthew  
28:5-7
