I had a dream where I killed the Devil?

Journal this it seems prophetic.. I think that the ending with the earth means about in Revelations means He makes an new hevean and a new earth and everything is made new. This world will pass away and we will live in the new jeruselum and Hevean will be with earth. I don't take it as a scary thing like He's crushing the earth haha, more like this one is passing away to make room for the new one. As far as the rest.. I don't really know ask the Holy Spirit to reveal it to you. You probably have the gift of prophecy or prophetic dreams
