Joseph continues what must have seemed his extraordinary level of interest in their family, and enquires about their father, while still hiding his true identity from them. Joseph loved his father as his father loved him, and longed to see him again.
It is their brother who speaks to them, but they do not know it. In our unconverted state, it is Christ, the Saviour, who addresses us, but at first we count him as our accuser, for we only know of his law which condemns us. We shrink from him, not understanding his purposes towards us.
Joseph can hardly control himself in front of them and we are taught that this is how Christ feels for us even before he reveals himself to us. He yearns for his elect people, and loves them with a love that passes knowledge. This is to the encouragement of those who are tempted to feel that God is only angry with them, and who feel that it is hopeless to expect to obtain mercy from him. ‘Behind a frowning providence, he hides a smiling face’, says Cowper. The seeker must not be put off by that frown. It is working for our good to humble us, and we must press nearer to him, and not shrink back.
Christ feels for us even before he reveals himself to us. Let no one despair of receiving grace at last. This passage is designed to teach us never to give up prayer, never to stop appealing to his mercy.
