John Gill Commentary John 10:2

"But he that entereth in by the door is the shepherd of the sheep." — John 10:2 (ASV)

But he that entereth in by the door
With a divine commission, and by a divine authority, who comes not of himself, but is sent; does not take the honour to himself, or thrust in himself, and assume an office to himself, but is called unto it, and invested in it, he

is the shepherd of the sheep ;
by whom Christ means himself, as is evident from (John 10:11John 10:14) , whose the sheep are, and who takes care of them, and feeds them, as a shepherd does his flock; and which holds true of any under shepherd, having his mission and commission, and deriving his authority from Christ.
