The Eternal Kingdom
The Kingdom of Heaven is the eternal reign and realm of God. It is not God, yet is inseparable from Him and His attributes. It is the perfect picture of government, as we understand such, in that it is perfectly just and righteous, perfectly merciful, humble, and powerful. Indeed all true human government derives itself from it.
We must not confuse the Kingdom with the church. The church is related to the Kingdom, and the Kingdom is related to the church, but we must not look at the outward expression of what we know as “church” and equate it with the Kingdom.
