Seven doors are open in heaven for spiritual perfection. Word of wisdom, Word of knowledge which gives understanding. The gift of faith which gives us the faith that Jesus had. Gift of healings, The working of miracles, Prophecy, The discerning of spirits.
Greater access to the gifts and power of the Spirit will come.
The key of David is required to open these doors. Jesus has the key of David and opens these doors for us when we become those who worship in spirit and in truth like David did. Worship will position us to go through these 7 doors as the Spirit of GOD wills and he will bring us through the door of whatever gift is needed at the time.
