Everlasting life does not mean that we get to go to heaven when we die. The dead will be resurrected.

For if the dead are not raised, then Christ has not been raised either. And if Christ has not been raised, your faith is futile; you are still in your sins. Then those also who have fallen asleep in Christ are lost. If only for this life we have hope in Christ, we are of all people most to be pitied. But Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep. (1 Corinthians 15:16-20)

Martha answered, "I know he will rise again in the resurrection at the last day." (John 11:24)

Martha believed that we would be resurrected on the last day.
