In Revelation 4, we come to the section about the future. John is included so he could see and understand the things that are to happen on earth. In turn, he would record this experience so we could all understand.
In this vision, John sees an open door up to heaven and a voice tells him to come up. He goes up and sees God sitting on a throne (v. 2). Qualities of God as king, governor, and judge sitting on a throne are extolled. A rainbow encircled the throne and surrounding the throne were twenty-four other thrones with twenty-four elders sitting on them. They were dressed in white and had crowns of gold (v. 4).

From the throne come flashes of lightening and in front of the throne, seven lamps were blazing (seven spirits of God). A sea of glass that is clear as crystal looked like it was in front of the throne (v. 6). John was given this vision to help us see what heaven will be like; a place far more beautiful than the human eye has ever seen or the mind ever imagined.
Most want to go to heaven some day but not right away. The good thing is that life is not really ended by death. For those of us who believe in Christ, it only changes because we make a great step from faith into vision when we leave this earth. We will someday find a life far more beautiful than we could ever imagine.
