At the heart of the argument is no other issue than what is the “Kingdom”. This was the heart of Jesus’ message, as He said, “What is the Kingdom of Heaven like, and to what shall I compare it?” (Luke 13:18).
We must comprehend what the Kingdom of God is, and what it is like, if we want to understand God’s plan of redemption, including His plan of Eschatology.
Correctly grasping what the Kingdom is like will set the tone for our Eschatology, and an incorrect understanding of the Kingdom of Heaven, or of God, will lead us to error somewhere along the path.
