I definitely believe in an afterlife, which is kind of a misnomer, since I believe the next life is only a continuation of this life.
The only difference is that the next life is conducted in a spiritual world, not a material world.
A friend asked: “How should one look forward to death?”
‘Abdu’l-Bahá answered: “How does one look forward to the goal of any journey? With hope and with expectation. It is even so with the end of this earthly journey. In the next world, man will find himself freed from many of the disabilities under which he now suffers. Those who have passed on through death, have a sphere of their own. It is not removed from ours; their work, the work of the Kingdom, is ours; but it is sanctified from what we call ‘time and place.’ Time with us is measured by the sun. When there is no more sunrise, and no more sunset, that kind of time does not exist for man. Those who have ascended have different attributes from those who are still on earth, yet there is no real separation.”
Nevertheless, I have a fair bit of anxiety about what the next life will be like, since it is unknown. I am anxious whenever I have to go to a place I have never been to, but in this life we can always look at the brochures and we know we can always come home. Such is not the case with the next life.
