In Mark chapter 16, Jesus gives His disciples
the Great Commission.

He is going to depart to be with the Father.
He will be seated at the Father's right hand.

Now Jesus' disciples are going to take His
place here on earth. They are to continue
His ministry. They will continue to do what
He was doing before He left.

So Jesus reveals that His ministry of healing
and salvation would be carried on by His
followers.
