Beatitude of Isaiah: When peace comes, everyone who has lived honestly will rest on his own bed. Isaiah 57:2

The Book of Isaiah covers an extensive period of time, and is divided into three parts; the first text is most likely from the prophet himself, and the following two are probably from one of his disciples. The third part of Isaiah is of the three books, the shortest text, and the third book is a text that invites the Israelites who survived the Babylonian exile to maintain their trust in God, to avoid idolatry, and to keep their faith in the ancient promises, at a time when only the ancient ruins of Jerusalem remained and everything was yet to be done; the book also hints at a distant future in which all nations will be called to the new Jerusalem, in accordance with all of Isaiah's prophecies about Jesus.
But the task of the prophets is not only to see the future or interpret mysterious texts, it is also to teach simple and common people the ways of God, because Israel needed to receive a new heart, no longer of stone but of flesh. And in a context of skepticism about the future, the prophet recalled the importance of righteous living and its reward the secure life, with a beautiful beatitude in his book: "When peace comes, everyone who has lived honestly will rest on his own bed" Isaiah 57:2.
With this spiritual teaching, the prophet Isaiah reminded to the israelites that every path has its reward, because just as the prophet reminded the believers that righteousness leads to the blessing of peace and security, the prophet condemned false fasting and idolatrous practices. And this is so because God is wise and has a plan for humanity, and Isaiah taught this spiritual truth with these words: "I, the LORD, love justice. I hate robbery and wrongdoing. I will faithfully reward my people's work. I will make an everlasting promise to them" Isaiah 61:8.
As a precursor to the Sermon on the Mount, the prophet Isaiah with great wisdom called the Israelites to heal their wounds and to seek God's mercy (compassion, gentleness, kindness) that gives men a new life, because a new earth and a new heaven had to rise from the ashes of the past, as the prophet said: "I will create Jerusalem to be a joy and its people to be a delight" Isaiah 65:18.
