This is John’s vision of Heaven given to him by an angel of God. John describes a standing door open in Heaven. Through it was a throne and a description of the one sitting on it. 

John goes on to describe unearthly creatures, elders all giving praise to the one who sits on the throne. 

I think of John’s excitement, praise, and humility in the face of these overwhelming wonders. This was a vision of Heaven! 

A song comes to mind as I read Revelation 4: I Can Only Imagine by MercyMe. 

I can only imagine what it will be like When I walk, by your side
I can only imagine what my eyes will see 

When you face is before me I can only imagine
I can only imagine Surrounded by You glory What will my heart feel 

Will I dance for you Jesus Or in awe of You be still
Will I stand in your presence Or to my knees will I fall 

Will I sing hallelujah
Will I be able to speak at all
I can only imagine
I can only imagine
I can only imagine when that day comes
When I find myself standing in the Son
I can only imagine when all I would do is forever Forever worship You
I can only imagine
I can only imagine
Surrounded by Your glory
What will my heart feel
Will I dance for You, Jesus
Or in awe of you be still
Will I stand in your presence
Or to my knees will I fall
Will I sing hallelujah
Will I be able to speak at all
I can only imagine
I can only imagine hey ya ah
Surrounded by Your glory
What will my heart feel
Will I dance for You, Jesus
Or in awe of you be still
Will I stand in Your presence
Or to my knees will I fall
Will I sing hallelujah
Will I be able to speak at all
I can only imagine
I can only imagine hey ya ah
I can only imagine yeah yeah
I can only imagine
I can only imagine ey ey ey
I can only imagine
