Matthew 5:1-12a , 1 John 3:1-3 and Revelation 7:2-4, 9-14

Matthew 5:1-12a
1 Then, seeing the crowds, he ascended the mountain, and when he had sat down, his disciples drew near to him,
2 and opening his mouth, he taught them, saying:
3 "Blessed are the poor in spirit, for theirs is the kingdom of heaven.
4 Blessed are the meek, for they shall possess the earth.
5 Blessed are those who mourn, for they shall be consoled.
6 Blessed are those who hunger and thirst for justice, for they shall be satisfied.
7 Blessed are the merciful, for they shall obtain mercy.
8 Blessed are the pure in heart, for they shall see God.
9 Blessed are the peacemakers, for they shall be called sons of God.
10 Blessed are those who endure persecution for the sake of justice, for theirs is the kingdom of heaven.
11 Blessed are you when they have slandered you, and persecuted you, and spoken all kinds of evil against you, falsely, for my sake:
12 be glad and exult, for your reward in heaven is plentiful.
1 John 3:1-3
1 See what kind of love the Father has given to us, that we would be called, and would become, the sons of God. Because of this, the world does not know us, for it did not know him.
2 Most beloved, we are now the sons of God. But what we shall be then has not yet appeared. We know that when he does appear, we shall be like him, for we shall see him as he is.
3 And everyone who holds this hope in him, keeps himself holy, just as he also is holy.
Revelation 7:2-4, 9-14
2 And I saw another Angel ascending from the rising of the sun, having the Seal of the living God. And he cried out, in a great voice, to the four Angels to whom it was given to harm the earth and the sea,
3 saying: "Do no harm to the earth, nor to the sea, nor to the trees, until we seal the servants of our God on their foreheads."
4 And I heard the number of those who were sealed: one hundred and forty-four thousand sealed, out of every tribe of the sons of Israel.
9 After these things, I saw a great crowd, which no one could number, from all the nations and tribes and peoples and languages, standing before the throne and in sight of the Lamb, clothed in white robes, with palm branches in their hands.
10 And they cried out, with a great voice, saying: "Salvation is from our God, who sits upon the throne, and from the Lamb."
11 And all the Angels were standing around the throne, with the elders and the four living creatures. And they fell upon their faces in view of the throne, and they worshipped God,
12 saying: "Amen. Blessing and glory and wisdom and thanksgiving, honor and power and strength to our God, forever and ever. Amen."
13 And one of the elders responded and said to me: "These ones who are clothed in white robes, who are they? And where did they come from?"
14 And I said to him, "My lord, you know." And he said to me: "These are the ones who have come out of the great tribulation, and they have washed their robes and have made them white by the blood of the Lamb.
