I hope my answer will be uninteresting and routine:

When I profess the creed with the congregations where I am worshiping, I don't gulp at the final words and indeed delight in them:

. . . and I look for the resurrection of the dead, and the life of the world to come. . . .

Translation: If I begin the creed with "I believe in a Creator. . . "and go on to witness to the reach and protection and love of God, then it makes more sense to assume that that love will not end with my physical death.

Explain? I have not the faintest idea. I like to quote theologian Karl Rahner who called death "the abyss of mystery," which is a way of saying that I/we have no words, concepts, reaches of imagination to make sense of that in ordinary conceptions. And I don't need that.

No, I have had no post-death experiences, and have not been moved by any testimonies by those who have. I wouldn't dream of talking them out of it, but just have to say that I do not find them convincing or helpful.

I'll just stay stuck with the beginning and end of the creeds, along with most of two billion others, even as we commend to God with hope and no sense of dismissal the hopes of those who are not Christian. It's not a contest of "our concept is better than your concept," but rather grateful acceptance of what little one grasps in the "abyss of mystery."
