Origen
Catena Aurea · Matthäusevangelium 19
Then answered Peter and said unto him, Behold, we have forsaken all, and followed thee; what shall we have therefore? And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the regeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel. And every one that hath forsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my name’s sake, shall receive an hundred fold, and shall inherit everlasting life. But many that are first shall be last; and the last shall be first.
Peter had heard the word of Christ when He said, If thou wilt be perfect, go and sell all that thou hast. Then he observed that the young man had departed sorrowful, and considered the difficulty of riches entering into the kingdom of heaven; and thereupon he put this question confidently as one who had achieved no easy matter. For though what he with his brother had left behind them were but little things, yet were they not esteemed as little with God, who considered that out of the fulness of their love they had so forsaken those least things, as they would have forsaken the greatest things if they had had them. So Peter, thinking rather of his will than of the intrinsic value of the sacrifice, asked Him confidently, Behold, we have left all.
