(28-31) Then Peter began to say unto him.--See Notes on Matthew 19:27-30. St. Mark omits the question which St. Matthew adds to St. Peter's words, "What shall we have therefore?"

Verse 28. - Peter began to say unto him, Lo, we have left all, and have followed thee. Peter began to say unto him. He had been thinking of himself and his companions, the other disciples.. He in reference to these last words of our Lord. It is probable that the sacrifice which Peter and the rest of the disciples had made when they became his followers, was small, compared with the sacrifice which our Lord demanded of the rich young ruler. Nevertheless they forsook their all, whatever it was. They had forsaken their boats and their nets. They had forsaken their means of subsistence. They had forsaken things which, though they were not much in themselves, were nevertheless such things as they would have desired to keep. Cornelins a Lapide says, "Such things are forsaken by those who follow Christ, as are capable of being desired by those who do not follow him." St. Augustine says, "St. Peter not only forsook what he had, but also what he desired to have. But who does not desire daily to increase what he has? That desire is cut off. Peter forsook the whole world, and he received in return the whole world. They were as those who had nothing, and yet were possessing all things."

10:23-31 Christ took this occasion to speak to his disciples about the difficulty of the salvation of those who have abundance of this world. Those who thus eagerly seek the wealth of the world, will never rightly prize Christ and his grace. Also, as to the greatness of the salvation of those who have but little of this world, and leave it for Christ. The greatest trial of a good man's constancy is, when love to Jesus calls him to give up love to friends and relatives. Even when gainers by Christ, let them still expect to suffer for him, till they reach heaven. Let us learn contentment in a low state, and to watch against the love of riches in a high one. Let us pray to be enabled to part with all, if required, in Christ's service, and to use all we are allowed to keep in his service.Then Peter began to say unto him,.... only observing that Christ promised treasure in heaven to the young man, provided he sold all that he had, and gave it to the poor; but being, in some measure, freed from that surprise and astonishment, which had seized him, and his fellow disciples, at the representation of the difficulty of a rich man's entering into the kingdom of God, by the last words; and taking heart from thence, began to take notice of the following case, as an instance and illustration of what Christ had said; for that same power, which had caused them to quit all their worldly substance for Christ, though it was but small, could also work a like effect upon the heart of a man ever so rich:

lo! we have left all, and have followed thee: in Matthew it is added, "what shall we have therefore?" See Gill on Matthew 19:27.
