Do we believe that there are two hells? Will there be a second chance for those currently in hell? I was asked this at Joshua's men and I felt dumb for not knowing about 2 hells.
I know that Joshua’s Men participants are reading through Wayne Grudem’s Systematic Theology this year. I’d encourage you to read chapter 41 (particularly the section titled “The Souls of Unbelievers Go Immediately to Eternal Punishment”). This should clear up the “are there two hells” part of your question. However, to answer your second question, there will not be a second chance for anyone to repent and receive Christ after they have died. That’s why it is important for us to share the Gospel while there is still time for them to turn from the sin and turn to Christ.
You mention God answers your question. How does the answer come? Is it a generic feeling?
God speaks to us in a variety of ways. Most clearly, He speaks to us through the Bible. That’s why it’s important for us to read, study, and memorize God’s Word. Additionally, God will speak to our spirit. This may be what you mean by generic feeling. The caution here is to always check these feelings with the Bible, as God will never contradict Himself. Finally, God speaks to us through others. That’s why Christian community (Life Groups at Gateway) are important.
Where did Josh's view on heaven and our eternal bodies come from?
My (Josh’s) view of heaven and our eternal bodies comes primarily from the Bible. I’d encourage you to read 1 Corinthians 15:35-58 and also the last two chapters of Revelation. Also, as I said in the sermon, Jesus’ resurrected body gives us clues, as well, as to what our eternal bodies will be like.
