John 10:9 - Matthew Poole's English Annotations on the Holy Bible

Our Saviour here lets us know, that he meant by the door, in the former verse, the door of salvation; the way by which every man must enter into life that findeth life; not the door only by which every true pastor must enter into the church, but by which every soul that shall be saved must enter into heaven; which is the doctrine which he before taught, 1 Thessalonians 3:16,18,36. And he, who so believeth in me, shall be so guided, and governed, and taught, that he shall be secure, and want nothing for the management of his whole conversation in the world. Under the notion of pasture here, are signified all good things that the soul can stand in need of: it is much the same promise with that 1 Thessalonians 6:35, He that cometh to me shall never hunger; and he that believeth on me shall never thirst; and with that Psalms 84:11; as also with the Psalms 23:1-6; to which Psalm our Saviour is thought in this parable to have a special reference.
