And those who've said that they have died and seen a light, come back from the dead, been in or have seen a vision of Heaven ...what message do they have for us??

Lazarus said, "I pray thee therefore, that thou would send him to my father's house: For I have five brethren; that he may testify unto them, lest they also come into this place of torment."

Abraham saith unto him, "They have Moses and the prophets; let them hear them."

And he said, "Nay, father Abraham: but if one went unto them from the dead, they will repent."

And he said unto him, "If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead."

It seems that Lazarus, (not the same Lazarus that Jesus brought back from the dead) had concern for those in his family that he loved.  Seems that he had a lot of love for his family.  Yet, it appears that ignorance was not bliss.

I would say that we all should have love for our family, with a concern that we have just read about.  Yet, that love goes beyond us ...and we should see that it's not about our love, but rather the love of Jesus.  And we should want others outside our family also not to be ignorant of it.
