Friend, we don’t know many of the details about what Heaven will be like. But that’s no reason to assume that our time on earth will be superior to spending eternity with Jesus in Heaven. Unless Jesus comes back while you’re still living, you will experience death. But, for Christians, there’s nothing but good news.
Consider Paul’s advice to Timothy about taking care of family. Bottom line up front: a person who claims to be a Christian and doesn’t take care of his family is worse than an infidel- a pagan, unbeliever, etc.
