Show me where it says Jesus did this while in the grave ?
There's three scriptures. None of them are very clear about where Jesus was for the three days between His crucifixion and resurrection. I haven't really studied this very closely but i will post them. I do feel that this is a side issue and that the more important core issue is that He dies for our sins, and was resurrected, that we may have life. I've always felt that He did go somewhere and perhaps (probably) collected the souls of the righteous dead.
One scripture is:
Ephesians 4:8-10
8 Wherefore he saith, When he ascended up on high, he led captivity captive, and gave gifts unto men.
9 (Now that he ascended, what is it but that he also descended first into the lower parts of the earth?
10 He that descended is the same also that ascended up far above all heavens, that he might fill all things.)/
Acts 2:29-31
29 “Men
and brethren, let
me speak freely to you of the patriarch David, that he is both dead and buried, and his tomb is with us to this day.30 Therefore, being a prophet, and knowing that God had sworn with an oath to him that of the fruit of his body, according to the flesh, He would raise up the Christ to sit on his throne, 31 he, foreseeing this, spoke concerning the resurrection of the Christ, that His soul was not left in Hades, nor did His flesh see corruption/
1 Peter 3:18-19
18 For Christ also suffered once for sins, the just for the unjust, that He might bring use]" style="font-size: 0.65em; font-weight: bold; vertical-align: top;"> to God, being put to death in the flesh but made alive by the Spirit, 19 by whom also He went and preached to the spirits in prison,/
The Acts passage speaks of being dead and buried, and that Jesus's soul was not left in hades. SO he was there for a few, right? In Ephesians it speaks about Him descending into the lower parts of the earth. This seems like it has to be talking about the same event, to me. And the 1 Peter passage sounds like it hints at what He did while He was there.
Like I said, I haven't really delved real deep into this, but I've heard it discussed here and there and a lot of scholars seem to hold that He went to Hades/hell/Sheol and did some preaching and collected the souls of those left in (Abrahams Bosom). It sounded reasonable enough to me and I went on to try an learn more important things, like relationship.
