Answer by George Townshend:
Jesus said to His disciples, "...lo, I am with you always, even unto the end of the world." (Matt. 28:20)
He also said to His disciples. "...I go away and come again unto you... (John 14:28)
These are two distinct promises. The first refers to His continuing presence through the Holy Spirit. The second to His departure and His return.
