Jesus Christ will establish his eternal, enduring kingdom. But why, after 2,000 years, has this still not come to pass? We find the answer in the story of King Saul and the incumbent King David.
King Saul sought to establish and preserve his own rule and kingdom. He threatened and tried to murder David, who would establish God's kingdom. King Saul fought against God's kingdom, even though he'd been made king for the purpose of establishing it.
Likewise, Christians will prevent the kingdom of God from coming on the earth so long as they fight for their own kingdom. That kingdom may be lifestyle, position, or simply “living MY life.”
However, “my kingdom” may also take on a religious nature, and pretend to be God's kingdom. For example, John Calvin participated in burning a fellow Christian at the stake. Why? Because the man opposed Calvin's “kingdom” of what he considered to be correct theology. This violates the first and greatest commandment to love God with all our heart, and our neighbor as ourselves.
Can you truly say that the zeal of God's house has eaten you up?
