Jesus (Yeshua‘) called God His Father in heaven. He is also our Father. In Matthew 5 Jesus taught that when we love our enemies we display the family likeness.
Heaven is not a geographical location, rather it is the spiritual dwelling of God. If we are in relationship with Him, we can experience His presence wherever we are. That closeness will continue for us forever.
