Our Lady in Medjugorje speaks to you about the reality of Purgatory

Message dated July 20, 1982
In Purgatory there are many souls and among them also people consecrated to God. Pray for them at least seven Pater Ave Gloria and the Creed. I recommend it! Many souls have been in Purgatory for a long time because nobody prays for them. In Purgatory there are several levels: the lower ones are close to Hell while the higher ones gradually approach Heaven.
Some passages from the Bible that can help us understand this message.
2 Maccabees 12,38-45
Judah then assembled the army and came to the city of Odollam; since the week was completed, they purified themselves according to usage and spent Saturdays there. The next day, when it had become necessary, the men of Judah went to collect the corpses to lay them with their relatives in the family tombs. But under the tunic of each dead they found objects sacred to the idols of Iamnia, which the law forbids the Jews; therefore it was clear to all why they had fallen. Therefore all, blessing the work of God, the just judge who makes the occult things clear, resorted to prayer, pleading that the sin committed was fully forgiven. The noble Judas exhorted all those of the people to preserve themselves without sins, having seen with their own eyes what had happened for the sin of the fallen. Then he made a collection, with a head each, for about two thousand silver dramas, sent them to Jerusalem to be offered an atoning sacrifice, thus performing a very good and noble action, suggested by the thought of the resurrection. Because if he had not had firm confidence that the fallen would be resurrected, it would have been superfluous and vain to pray for the dead. But if he considered the magnificent reward reserved for those who fall asleep in death with feelings of pity, his consideration was holy and devoted. So he had the atoning sacrifice offered for the dead, to be absolved of sin.
2.Peter 2,1-8
There have also been false prophets among the people, as well as there will be false teachers among you who will introduce pernicious heresies, denying the Lord who redeemed them and attracting a ready ruin. Many will follow their debauchery and because of them the way of truth will be covered with impropèri. In their greed they will exploit you with false words; but their condemnation has long been at work and their ruin is lurking. For God did not spare the angels who had sinned, but precipitated them into the dark abysses of hell, keeping them for judgment; he did not spare the ancient world, but nevertheless with other sects he saved Noah, auctioneer of justice, while making the flood fall upon a world of wicked; he condemned the cities of Sodom and Gomorrah to destruction, reducing them to ashes, setting an example to those who would live impiously. Instead, he freed the just Lot, distressed by the immoral behavior of those villains. The righteous one, in fact, for what he saw and heard while he lived among them, tormented himself every day in his soul just for such ignominies.
Revelation 19,17-21
Then I saw an angel, standing on the sun, shouting loudly to all the birds that fly in the middle of the sky: “Come, gather at the great banquet of God. Eat the meat of the kings, the meat of the captains, the meat of the heroes , the meat of horses and riders and the meat of all men, free and slaves, small and large ". Then I saw the beast and the kings of the earth with their armies assembled to wage war against the one who was sitting on the horse and against his army. But the beast was captured and with it the false prophet who in his presence had operated those portents with whom he had seduced those who had received the mark of the beast and had adored the statue. Both were thrown alive into the lake of fire, burning with sulfur. All the others were killed by the sword that came out of the Knight's mouth; and all the birds were satisfied with their flesh.
