Is there salvation after death?
Yes and no. It is written: 1 Peter
19: By which also he went and preached unto the spirits in prison;
20 Which sometime were disobedient, when once the longsuffering of God waited in the days of Noah, while the ark was a preparing, wherein few, that is, eight souls were saved by water.
This verse tells you, who, what and when. Those who perished in the flood were given a chance to accept and repent. I would imagine that some did and some didn't just like when he preached on earth. Other situations are very clear. Like someone who has heard the word and has clearly rejected Christ has sealed their fate. Some who had become Christians then walked away, well the bible is clear about that. What about a young child that dies that wasn't capable of understanding salvation. This fits into what some say that if you die without accepting Christ your going to hell. According to them there are a lot of children in hell. What about someone that has never heard about Christ? They die, so according to some they are going straight to hell. A physical death is not a barrier to God in all reality it is irrelevant since all are alive as God see's it. The body is only a tent for the spirit just because the tent gives way doesn't mean the spirit is lost forever. It is written: I will have mercy on whom I will have mercy and I will have compassion on whom I will have compassion. This applies whether in the physical or in the spirit. God is not bound by the very finite understanding of the human mind. So again the answer is yes and no.
