The soul survives after the death of the body. Such is the teaching of Divine Revelation. The following are some texts:
Survival of the soul
1 Samuel 28,3-19: Samuel’s soul, after his death, speaks to Saul. Some claim that it was not Samuel, but the demon who spoke to Saul. And yet, the text reveals that it was Samuel. And Samuel’s predictions were fulfilled, a sign that it was not the lying devil.
Matthew 17,1-8: Moses and Elijah appear next to Jesus at the Transfiguration. It is true that Elijah, according to the Bible, did not die: he was removed up to Heaven in his body (2 Kings 2,1-13), but Moses died (Deuteronomy 34,5-7). It is therefore Moses’ soul that appeared.
Luke 16,19-31: The souls of Abraham, of poor Lazarus, and of the bad rich man, exist after their death.
Luke 23,43: “In truth, I tell you, today you will be with me in Paradise”, Jesus says to the thief who repented on the cross.
1 Peter 3,18-20: Jesus’ soul, between his death and his resurrection, visits the souls of those who died in the past to announce his Advent.
Revelation 6,9: John sees the souls of the martyrs.
Resurrection of the bodies
Matthew 27,52-53: The bodies of many holy people rose from the dead after Jesus’ resurrection.
Luke 20,27-39: Jesus answers the Sadducees who didn’t believe in the resurrection: “The Lord is God of Abraham, God of Isaac and God of Jacob. Now, He is not God of the dead, but of the living”. This text explains the survival of the soul and the resurrection of the body.
John 5,28-29: The resurrection of the dead revealed by Jesus.
John 6,54: Jesus said: “Who eats my flesh and drinks my blood has the eternal life and I will resurrect him on the last day.”
1 Corinthians 15,12-57: “How is it that some among you say that there is no resurrection of the dead!”. Paul explains the resurrection of the bodies and blames those that do not believe therein.
In spite of these evident biblical confirmations on the survival of the soul after death, and the resurrection of the body, some “supposed” believers do not believe in them. Their arguments are a fabric of incoherence.
