Below are some revelations of God’s glorious plan for humanity, confirmed with the symbolism of the number seven:

God created the world in seven days (Genesis 1)

Seven thousand years of human history

Seven covenants

Seven ages of the church (Revelation 1:4)

Seven each of every clean animal into the ark for sacrifice (Genesis 7:2)

Priest sprinkled the leper with blood seven times and with oil seven times (Leviticus 14)

Seven feasts (Leviticus 23)

Seven stations of the tabernacle: seven revelations of Jesus Christ

Seven manifestations of the Holy Spirit

Within the seven manifestations, Isaiah 11 reveals sevenfold revelations of the Holy Spirit

The seven “I am” revelations in the Gospel of John:

Jesus shed His blood seven times

Seven Spirits of God:

“Seven lamps [torches] of fire were burning before the throne, which are the seven Spirits of God” (Revelation 4:5).

Seven Spirits of God sent out into all the earth:

In the midst of the throne, “stood a Lamb as though it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent out into all the earth” (Revelation 5:6).
