Isaac of Nineveh

When a man overcomes justice by mercy, he is crowned, though not with crowns awarded under the law to the righteous, but with the crowns of the mature who are under the gospel. The ancient law also dictates that a man must give to the poor from his own means, and clothe the naked, and love his neighbor as himself. It forbids injustice and lying. But the perfection of the gospel’s dispensation commands the following: “Give to every man that asks of you, and of him that takes away your goods ask them not again.” And further, a man must not merely with joy suffer injustice as regards his possessions and the rest of the external things that come upon him, but he must also lay down his life for his brother. This is the merciful man.

“The kingdom of the heavens is within you.” You should not hope to find it in a place. It does not come in observation, according to the word of Christ.
