I have eternal life now this means I'm in Christ and He is in me right?
Yes, having eternal life means having Christ, who IS eternal life. So, He is in you and you are in Him.
So my sins are forgiven now and when I die here I will continue on in him for eternity is this correct?
Yes, your sins have been forgiven for all time. There is no end to Christ ... there is no end to you! :)
It seems like ever thing I have been raised to believe is being shaking lately Is there a hell and who is it for?
As far as "hell" goes we have come to assume an awful lot. We have had centuries of religious teachings and pictures of devils and fire and brimstone, etc. etc. If you read your Bible you will find some mentions of hell here and there, but most of what we have heard is a compilation of various references all crammed together that have been fit into pagan concepts stolen from the Greeks and Romans. For example, Paul doesn't mention hell in his whole dissertation of the gospel in the letter to the Romans. But he does deal with condemnation and how Christ has taken it out of the way. Those who have not passed from death into life through Christ are still living in condemnation. There are a lot of passages that I am still considering regarding this, so don't think I have it altogether! :) haha
Also what is Heaven?
Our concepts of heaven are intertwined with mythology. We have come to view it as the "good place" for those who have done "good" or the perfect place of eternal bliss. So, why do we still try to retain the place of that concept? In the letter to the Ephesians, Paul writes about "the heavenly places" ... better translated "the heavenlies" ... simply stated, the realm of God. Try as we may, we can't seem to be able to picture a "place" that contains the reality of new life in Christ. I don't think it is very important ... and actually has proven to be against the truth of grace for we talk about the size and position of our "mansions" based on our performance. So, what I'm saying is that "heaven" as we know it is a lie and a myth. Being IN Christ which makes us partakers of the divine life (the heavenlies) both now and forever is far superior to any version of an improved existence as we know it.
I hope this is some help to you.
