Q. 1. I noticed in the New Testament, there is a reference to Jesus descending into hell after He died. Why did Jesus go to hell?
A. 1. Your reference to Jesus descending into hell comes from the following Bible passage:
"For Christ also suffered for sins once for all, the righteous for the unrighteous, in order to bring you to God. He was put to death in the flesh, but made alive in the spirit, in which also he went and made a proclamation to the spirits in prison, who in former times did not obey, when God waited patiently in the days of Noah, during the building of the ark, in which a few, that is, eight persons, were saved through water." [1 Peter 3:18-20]
The word referring to Jesus having gone to proclaim the Good News to the spirits in "prison" is often quoted as in "hell" or in "hades." No matter what word is used in modern Bible translations, that often do not reflect accuracy, in this particular case, it is a reference to Jesus descending into the spirit world known as "limbo" rather than the world of the wicked. Prior to the glorious resurrection of the Lord Jesus, "limbo" was the spiritual world where the saved waited to be taken into Heaven. Jesus was the First of many to enter the Kingdom of Heaven. [Romans 8:29]
Since the resurrection of Jesus, there is no reason for this particular spiritual world called "limbo" to exist. This is not the same limbo as the place where the unbaptised go to wait for Judgment Day.
