Three reasons:
1) God said, “Write it down"
2) The prophets spoke (wrote) and it happened like they said
3) Jesus quoted what they said.
He did to some men. They were called “false prophets”.
There are three groups of people mentioned in the Bible and that being “Jews, Gentiles, and those who belong to the Church of Godr:
1 Corinthians 10:32 Give none offence, neither to the Jews, nor to the Gentiles, nor to the church of God:
So the first thing we have to do is see to whom is he speaking to. His audience isn’t the Gentiles nor is he speaking to the church of God. He is speaking to the Jews. So, to apply “few” to “Church of God” would be to apply a message targeting to a specific group to a group that he wasn’t being addressed.
What we do know is that
Next, we also have to address context. There are multiple points.
1) He mentions to the Jews “False Prophets” vs “The Gate - Jesus” - so we can say that it is narrow as compared to false prophets.
2) He mentions the who call Jesus “Lord” who he doesn’t recognize. God is the judge of hearts, not me and not you.
3) The best method we can hope to understand is to look at the fruit of the tree.
Last, our view of “few” may not be God’s view of few. When we add all the people that will be accepted, it has been mentioned in Rev 7:9
After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands; 10 And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb.
That doesn’t sound like the “few” that you are talking about.
There is no scripture on “purgatory”. I find that to be a false doctrine.
I find that to be a wrong view on this scripture. The original Greek had no commas, question marks, colons or periods or even capital letters.
2 And his disciples asked him, saying, Master, who did sin, this man, or his parents, that he was born blind? This was the question.
3 Jesus answered, Neither hath this man sinned, nor his parents - Question answered
But, that the works of God should be made manifest in him. 4 I must work the works of him that sent me, while it is day: the night cometh, when no man can work. So, it did not matter how but rather Jesus came to bring the Kingdom living to the earth and healed the man.
Again… you can’t take one scripture and forget the rest of the scriptures. Jesus said, John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
Notice he didn’t say “live a perfect life” but rather simply “Believes”. Of course we should strive to live right, but it isn’t the basis for relationship. Paul reiterates it when he said, “Not by works lest any man should boast, it is a gift from God”. Ephesian 2:9
Maybe you should be judging the spirits like the Bible said we should? I don’t see any support given by Jesus, the prophets or the Apostles to support that position.
As I said above, if there is no scriptural support, we should question, instruct.
