I've been struggling with that question for a while now. What is next? Different things make me think of it. Of course, it's a wonder. I wonder. You wonder. Everyone wonders. How will it be when the life we have is finished?
No! I don't know and I'm not going to try to convince you of anything very much. A person's idea of the afterlife is effected by what they have been taught - directly or indirectly. Some people don't think about it. Some don't believe in it at all. Some think of heaven as a special place in their own mind's eye.
I believe in God. I believe in Jesus Christ and that he is God, the son of God. If you do as well, check out in your Bible the first letter Paul sent to the people of Corinth not long after Jesus died. In the 15th chapter of that letter, verses 35-49, he explains that we are fools if we think we will have human bodies in the afterlife. We will have a heavenly body; a spiritual body. It won't look like our human body. We won't have human needs. Our heavenly body will be different but distinct.
Paul also references Jesus' parable about the seeds. A farmer spreads seeds; some on the pathway, some in rocky ground, some in weedy ground and others in good earth. They have varying success. This time, going back and reading this parable, I think - not of the good things I can do as the farmer but that God is the farmer and we are the seeds. We are seeds all our lives. Seeds do not become all they can be without dying. It is in death that seeds sprout into a plant. It is in death that we can become all we can be. Like the farmer, only God knows what we will become; what we will look like and what abilities we will have.
We must live as Jesus taught us to live. We will become what God wanted us to be.
