"And I beheld, and, lo, in the midst of the throne and of the four beasts, and in the midst of the elders, stood a Lamb as it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent forth into all the earth." Rev 5:6

seven horns - omnipotence (perfect power)
seven eyes - omniscience (perfect perception)
seven spirits into all the earth - omnipresence (perfect pervasion)
