Believing 1 Peter 3:18-20 teaches Jesus was spiritually alive as a disembodied soul, and only physically dead after his crucifixion, can lead to Biblical contradictions as that belief requires a redefinition of death. The Bible defines the dead, as knowing nothing, unaware of what the living are doing. Their love, hatred and envy are gone and it is as if they are asleep, or unconscious. God the Father has always been alive and has never taken a human form. Jesus was alive as the Word before he became human. Remaining alive, he was born to Marry, demonstrating life does not depend on a physical body. When Jesus died and came back to life 3 days and nights later, it was not his physical form that gave him life, it was his consciousness that made him alive. When we have any level of consciousness it cannot be said we are dead, but living with a physically handycap. Why would Paul instruct the living to strive for immortality and eternal life if humans already had an immortal soul? Are God’s gifts, things we already have? Do you have to be alive to be held in contempt? What do the dead awake from, if they don’t lose consciousness when they die?
Romans 2:7 King James Version
To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
Daniel 12:2-3 Revised Standard Version
2 And many of those who sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt. 3 And those who are wise shall shine like the brightness of the firmament; and those who turn many to righteousness, like the stars for ever and ever.
1 Corinthians 15:20 Easy-to-Read Version
But Christ really has been raised from death—the first one of all those who will be raised.
Daniel 6:26 New King James Version
I make a decree that in every dominion of my kingdom men must tremble and fear before the God of Daniel. For He is the living God, And steadfast forever; His kingdom is the one which shall not be destroyed, And His dominion shall endure to the end.
John 1:1-5 International Children’s Bible
1 Before the world began, there was the Word. The Word was with God, and the Word was God. 2 He was with God in the beginning. 3 All things were made through him. Nothing was made without him. 4 In him there was life. That life was light for the people of the world. 5 The Light shines in the darkness. And the darkness has not overpowered the Light
