Mark 10:24

(ubi sup.) But the Lord said this to His disciples, who were poor and possessed nothing, in order to teach them not to blush at their poverty, and as it were to make an excuse to them, and give them a reason, why He had not allowed them to possess any thing. It goes on: And the disciples were astonished at his words; for it is plain, since they themselves were poor, that they were anxious for the salvation of others.

Therefore the Lord unfolds the words of His former saying to His astonished disciples, as follows: But Jesus answereth again, and saith unto them, Children, how hard it is for them that trust in their riches to enter the kingdom of God. Where we must observe that He says not, how impossible, but how hard; for what is impossible cannot in any way come to pass, what is difficult can be compassed, though with labour.

He says not here, that riches are bad, but that those are bad who only have them to watch them carefully; for He teaches us not to have them, that is, not to keep or preserve them, but to use them in necessary things.
