Luke 18:30

It says, "Peter said to him, 'Look, we have left all and followed you.' " …I imagine, to this some may reply, "What had the disciples given up? They were men who gained the necessities of life by their sweat and labor, being by trade fishermen, who perhaps owned a boat and nets somewhere. They did not have well-built houses or any other possessions. What did they leave, or for what did they ask a reward from Christ?" What is our answer to this? For this very reason, they made this most necessary inquiry. Since they possessed nothing except what was trifling and of slight value, they would learn how God will reward and gladden with his gifts those who likewise have left but little for the sake of the kingdom of God. They desired to be counted worthy of the kingdom of heaven because of their love for him. The rich man, one who has disregarded much, will confidently expect a reward. He who possessed little and abandoned it, how was it not right to ask what hopes he might entertain? For this reason, as representing those in the same condition of their having left little, they say, "Behold, we have left all and followed you." It is further necessary to observe also this. Correctly considered, the pain of abandoning is the same whether one abandons much or little. Come and let us see the real meaning of the matter by a trivial example. Suppose two men had to stand naked. The one took off expensive clothes while the other put off only what was cheap and easy to get. Would not the pain of the nakedness be equal in both cases? What possible doubt can there be on this point? As far as regards obedience and good will, those who had different circumstances and yet practiced equal readiness and willingly sold what they had must be placed on an equal footing with the rich. The very wise Paul also takes up their cause. […]

Thirdly, as to the enrichment of poverty through grace, it is added: And not receive much more in this time: which is not to be understood of temporal things, so that he would have many more wives, or children, or carnal brothers, but it is …

He said to them: "Truly I tell you, there is no one who has left house, or parents, or brothers, or wife, or children for the sake of the kingdom of God, who will not receive much more in this time, and in the age …

The sense then is this; He who in seeking the kingdom of God has despised all earthly affections, has trampled under foot all riches, pleasures, and smiles of the world, shall receive far greater in the present time. Upon the ground of this declaration, some of the Jews build up the fable of a millennium after the resurrection of the just, when all things which we have given up for God's sake shall be restored with manifold interest, and eternal life be granted. Nor do they from their ignorance seem to be aware, that even if in other things there might be a fit promise of restoration, yet in the matter of wives, who might be according to some Evangelists an hundred fold, it would be manifestly shocking, especially since our Lord declares that in the resurrection there will be no marrying. And according to Mark, those things which have been given up, He declares shall be received at this time with persecutions, which these Jews assert will be absent for a thousand years.

At this, Peter asks: "behold, we have left everything," and he asks not for himself alone, but for the consolation of all the poor. Lest only the rich have good hopes of receiving much, as those who renounced much, while the poor have no hope, …
