Most Christians have concerns about Heaven: What will we be like? Will I know what's happening on Earth? Will we be bored? Will we still be married or have a purpose? It's completely normal to have concerns about Heaven - we're trying to understand things based on our own ability, and we can't understand something so perfect! It's understandable to fear something you can't comprehend, but when you trust God and His goodness, you look forward to joining Him in Heaven.
