Proclamation of the Kingdom: Learn to do right; seek justice. Defend the oppressed. Isaiah 1:17

Isaias is one of the prophets who anticipate the arrival of the Kingdom of God with his vision. Isaiah explains one of the central messages of the Gospels, the proclamation of the Kingdom of God is to fight against oppression:
"Learn to do right; seek justice.
Defend the oppressed.
Take up the cause of the fatherless;
plead the case of the widow.", Isaiah 1:17.
The prophet Isaias compares the people of God with a beautiful vineyard that has not borne fruit, the religiosity without mercy, it is an empty religiosity and without content:
"I will sing for the one I love a song about his vineyard. My loved one had a vineyard on a fertile hillside.
He dug it up and cleared it of stones and planted it with the choicest vines. He built a watchtower in it and cut out a winepress as well. Then he looked for a crop of good grapes, but it yielded only bad fruit.", Isaiah 5:1-2
The prophet at the end of the parable puts more emphasis on the teaching: "The vineyard of the LORD Almighty is the nation of Israel, and the people of Judah are the vines he delighted in.", Isaiah 5:7.

Jesus also compares the Kingdom to us with a vineyard: "I am the true vine, and my Father is the gardener", John 15:1.
The Kingdom of Heaven is progressive, incremental; righteousness, mercy, piety are qualities that develop gradually in us and in society, like the vine that bears fruit, like the mustard seed that grows, like the leaven that rises.
Fighting against oppression and fury, establishing righteousness among men, doing justice and mercy to those who, due to their helplessness, cannot return our efforts, that is to bear good fruit and draw closer to God; This is what the prophet Isaiah asks of his people. Otherwise the judgment of providence inevitably draws near, all our actions are subject to the law of harvest and sowing: "Do not be deceived: God cannot be mocked. A man reaps what he sows.", Galatians 6:7.
