Really? You think to lecture me on how God made us per the Hebrews 4:12 Scripture? And do you really think... you can change the meaning of what Apostle Peter said in those 1 Peter 3 and 1 Peter 4 Scriptures about Jesus preaching The Gospel to the "dead"?
Let me LECTURE YOU on the proper interpretation of The New Testament meaning of "spirit". First, look at the Greek word for "spirit" in the following 2 verses...
Heb 4:12
12 For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
KJV
"spirit" above = NT:4151 'pneuma'
1 Peter 3:18-19
18 For Christ also hath once suffered for sins, the just for the unjust, that He might bring us to God, being put to death in the flesh, but quickened by the Spirit:
19 By which also He went and preached unto the spirits in prison;
KJV
"spirits" above = NT:4151 'pneuma' SAME WORD!
BRETHREN IN CHRIST:
I see that kind of thing DJT_47 tried to do all the time. They start out with their 'I know more than you' attitude about The Scriptures with claiming 'you first must know what the word ___ means'. Reminds me of Bill Clinton when being interrogated on some of his sexual escapades, and he said something like, "It depends on the what the word 'is' means".
Don't fall into those silly traps by those who seek to twist the simplicity of God's written Word.
Apostle Peter was revealing how at Lord Jesus' resurrection, He went and PREACHED THE GOSPEL to the DEAD souls of those who had died all the way back to the flood of Noah's day.
It does not say anything... about Christ's preaching The Gospel to those when they were alive, SIMPLY because for that to happen, Jesus would have had to have been born in the flesh BACK IN NOAH'S DAY! So just by that simple logic WE KNOW Peter was talking about Jesus at His resurrection preached to DEAD SPIRITS in that other dimension of Spirit!
And that Greek word for "spirits" CAN AND DOES ALSO APPLY to anyone born in the flesh that has died!
