Immortality or Death?

What is it like to be immortal, to not experience pain and death anymore?  There are those in the Bible who had a glimpse of what it was like to not feel pain or death, in certain examples.  Christ, when He was on the earth, was able to resurrect people from the dead.  We will all experience that in the near future when Christ returns, a chance to be in God's kingdom and have everlasting life.
