Origen
Patristic
c. A.D. 184–253
“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.”
