If you think about the spiritual health of the Church, we can see in history how the errors came out in doctrine because people did not know the Scriptures nor did they know the power of God.
When it comes to living, death is an immediate afterthought. At death, all our earthly hopes, joys and connections are taken away. How terrible it must be for one to look for nothing better beyond the grave.
Blessed be the God and Father of our Lord Jesus Christ! By his great mercy he has given us a new birth into a living hope through the resurrection of Jesus Christ from the dead – 1 Peter 1:3
“If we consider properly the doctrine of Scripture, the life of the soul, apart from the hope of the resurrection, will be a mere dream; for God does not declare that, immediately after the death of the body, souls live, — as if their glory and happiness were already enjoyed by them in perfection, — but delays the expectation of them till the last day… Since the Scriptures inform us that the spiritual life depends on the hope of the resurrection, and that souls, when separated from the bodies, look forward to it, whoever destroys the resurrection deprives souls also of their immortality.”
The same day some Sadducees came to him, saying there is no resurrection; and they asked him a question, saying, “Teacher, Moses said, “If a man dies childless, his brother shall marry the widow, and raise up children for his brother.’ Now there were seven brothers among us; the first married, and died childless, leaving the widow to his brother. The second did the same, so also the third, down to the seventh. Last of all, the woman herself died. In the resurrection, then, whose wife of the seven will she be? For all of them had married her.” Jesus answered them, “You are wrong, because you know neither the scriptures nor the power of God. For in the resurrection they neither marry nor are given in marriage, but are like angels in heaven. And as for the resurrection of the dead, have you not read what was said to you by God, “I am the God of Abraham, the God of Isaac, and the God of Jacob’? He is God not of the dead, but of the living.” Matthew 22:23-32
