Jesus' description of heaven
In the Gospel of Luke, Jesus describes heaven as paradise whilst on the cross.
'And he said to him, “Truly, I say to you, today you will be with me in Paradise." '(Luke 23:43)
Jesus also speaks about heaven to his disciples in the Gospel of John.
'My Father’s house has many rooms; if that were not so, would I have told you that I am going there to prepare a place for you?' (John 14)
This implies that there is enough room in heaven for all of those who repent
