In the Catholic traditions some miracles have been attributed to Saints after life. The Guardian should be a good source to read this. I know some people may have different views about the Catholic faith, but this post is not about this. The below about a 15 year old boy called Carlos Acutis.
" In May 2024, the medical board of the dicastery announced that it had verified a second miracle attributed to Acutis. The healing occurred two years earlier, after a woman named Liliana, from Costa Rica, visited Acutis’s tomb in Assisi. Liliana’s daughter, Valeria, had fallen off her bike while she was studying at a university in Florence, and had been hospitalised with severe head trauma. According to the Vatican, Valeria “required craniotomy surgery and the removal of the right occipital bone to reduce pressure on her brain”. Doctors gave her a low chance of survival. At Acutis’s tomb, Liliana asked him to heal her daughter. That same day, Valeria’s doctors reported that she had begun breathing on her own again; a few days later, all signs of the haemorrhage had gone. Upon reviewing the incident, the medical board of the dicastery could find no scientific explanation for what had occurred. Pope Francis declared it a miracle and said that he would convene a meeting called a consistory of cardinals to formally approve Acutis’s canonisation".

Btw, owing to discussion between myself and another forum member I thought that I would summarise what the Christian faith says about afterlife.
If Christians are not judged as doing the will of God in their lives to a level that is necessary in their lives they may be witnessed as being unbelievers.
What Jesus says about eternal life for believers.
(John 11:25-26) “ Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live: And whosoever liveth and believeth in me shall never die. Believest thou this?”
(John 6:47) “ Verily, verily, I say unto you, He that believeth on me hath everlasting life.
(Matthew 7:21-23)
" Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity"
(Revelation 2)
" I know thy works, and thy labour, and thy patience, and how thou canst not bear them which are evil: and thou hast tried them which say they are apostles, and are not, and hast found them liars:
And hast borne, and hast patience, and for my name's sake hast laboured, and hast not fainted. Nevertheless I have somewhat against thee, because thou hast left thy first love. Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent."
(Matthew 7:13-14)
"Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it."
(Luke 23:39-43)
“And one of the malefactors which were hanged railed on him, saying, If thou be Christ, save thyself and us. But the other answering rebuked him, saying, Dost not thou fear God, seeing thou art in the same condemnation?
And we indeed justly; for we receive the due reward of our deeds: but this man hath done nothing amiss. And he said unto Jesus, Lord, remember me when thou comest into thy kingdom. And Jesus said unto him, Verily I say unto thee, Today shalt thou be with me in paradise.”
(2 Corinthians 5:8) “We are confident, I say, and willing rather to be absent from the body, and to be present with the Lord.”
(Hebrew 4)
Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it... For we which have believed do enter into rest.
(Romans 8:13-16)
“For if you live according to the flesh, you will die; but if by the Spirit you put
to death the deeds of the body, you will live. The Spirit itself beareth witness with our spirit, that we are the children of God and if children, then heirs, heirs of God and joint heirs with Christ.”
What happens after the 2nd Judgement for believers at the judgement Seat of Christ.
(John 5:22) “For the Father judgeth no man, but hath committed all judgement unto the Son.”
(2 Corinthians 5:10) “For we must all appear before the judgement seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad”.
These events are suggested in (Revelation 19:7-8) and (Revelation 22:12) "And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be".
Christ will determine if we go to heaven or the New Earth after the 2nd Judgement.
Catholics believe in purgatory before entering God's kingdom for some believers.
