Open door

It reminds me of the scripture in the Bible, Rev. 4:1
After this I looked, and behold a door standing open in Heaven!

The natural is so closely related to the spiritual realm.
Many times it is parallel truth.
Like in the parables where Jesus takes situations out of the natural,
putting it in a metaphor.
God is giving open doors, Revelation, visions of Heaven,
Divine opportunities to step into.
