Well, I know that Jesus rebuked the Sadducees for their doctrine concerning marriage in heaven, which they used to try and trip Jesus up (Matthew 22:23-34).Jesus tells us we aren't given into marriage in heaven. So, if a person was married once, or twice, or more time on Earth, then he or she will not be married in heaven. Something happens that is hard to understand... and for some, difficult to accept... we won't be partnered with our "other half" in heaven. Our gender roles only serve purpose on Earth.We are not given into marriage in heaven because such partnering is no longer necessary or required for any level of survival or living. So then, once we are all in our new bodies, why would God give us the sexual parts (not just organs, but all things that identify us as male or female) if such parts will be useless and without purpose? Does God do things without purpose? I do not believe so, therefore, there will be no gender in heaven, as we are not given into marriage in heaven, and such parts that make us gender specific would be pointless... and God does not do what is pointless.
