Married people who make it to the Celestial kingdom, get to have their own... whatever, planet, universe, something... and make a world or worlds, similar to this one.

We are promised that if we are faithful, we will become "joint heirs with Christ." And what is Christ the Heir to? Everything that God (our Heavenly Father) has. That has no limitations. Romans 8:16-17; 16 The Spirit itself beareth awitness with our spirit, that we are the children of God:  
17 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.

god loved us and still does he wants us to be happy and he wants us to be like him so if i live my life that way i will be like him

We will become gods someday like our heavenly father. God wants us to become like him and Christ and in order to become more like God we have to become gods and that makes sense to me and we have to become like our Father in Heaven to recieve perfect joy in Heaven. The Bible says that we will be joint heirs with christ and recieve all thet he has and He is a god so that means becoming a god also.!
