For some reason, my thoughts always come back to the Kingdom. Maybe it's because Jesus' message was primarily about the Kingdom of God. In Mark's Gospel, he says that when Jesus left the desert after His temptation, He immediately went into Galilee and summarized His preaching this way: "The Kingdom of God is near. Repent and believe the good news!" The Kingdom is mentioned around 150 times in the New Testament. Maybe I'm wrong, but it seems to me there is little emphasis on the Kingdom in evangelical preaching these days.
I think to understand Jesus' preaching, we have to understand the Kingdom of God (or the Kingdom of Heaven). When we look at His teaching through the lens of the Kingdom, I think we understand Jesus much better.
I think, very simply, we can define the Kingdom of God as "anywhere the will of God is being done." Isn't that what a Kingdom is, essentially--a place where the King is in charge? On earth, Kingdoms are always territories, but that's not the case with the Kingdom of God. His Kingdom is a spiritual Kingdom.
Now some people might disagree with this description saying that God's will is ALWAYS being done; that anything that happens is God's will. I, however, don't believe that's the case. I don't think God always gets His way. He could always get His way if He wanted, but the Bible tells us that God has limited Himself out of love. Clearly, humans can oppose the will of God. 2 Peter 3:9 says it's not God's will that anyone would perish, but that all would come to repentance. That doesn't always happen.
But what are the signs of the Kingdom? How can we describe the Kingdom of God? Let's take a spin around the New Testament to see what it says.
First, we the Kingdom is a spiritual Kingdom, that we're not to make any nation or church on earth out to be the Kingdom. When Pilate questions Jesus about the accusation the Jews made that Jesus claimed to be a king (whose kingdom would seek to overthrow the Romans), Jesus replied (John 18):
Pilate then went back inside the palace, summoned Jesus and asked him, "Are you the king of the Jews?"So clearly Jesus didn't see the Kingdom as an earthly government or regime. It's spiritual.
"Is that your own idea," Jesus asked, "or did others talk to you about me?"
"Am I a Jew?" Pilate replied. "It was your people and your chief priests who handed you over to me. What is it you have done?"
Jesus said, "My kingdom is not of this world. If it were, my servants would fight to prevent my arrest by the Jews. But now my kingdom is from another place."
We also see that the Kingdom of God is turned upside-down. Look at Matthew 20:25ff
Jesus called them together and said, "You know that the rulers of the Gentiles lord it over them, and their high officials exercise authority over them. Not so with you. Instead, whoever wants to become great among you must be your servant, and whoever wants to be first must be your slave— 28 just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many."The way Kingdom people go about things is completely different than the way the people of the world do things.
Another similar passage that I find interesting is this one in Matthew 16.
Whoever wants to be my disciple must deny themselves and take up their cross and follow me. For whoever wants to save their life will lose it, but whoever loses their life for me will find it.When Jesus says this, He's really contrasting the Kingdom of God with the kingdom of this world. So many things we chase after are really values only in this world--money, fame, "success", reputation, etc. Those things aren't Kingdom values. When Jesus says we often try to "save our lives," He means that we worry so much about these values and we sell our soul for them. But Kingdom people run the opposite way. Their goal is not money (though we need it), and it's not what the world calls success, and it certainly isn't their reputation and standing up for their rights. If they were worried about that, they would do things a lot different.
We sometimes get frustrated in life when we try to live in the two worlds. Ultimately, we'll try to synthesize the two worlds and end up with a confused mish-mash of competing values. Christians will often talk about things like integrity and honesty, yet cheat to get ahead. They know God values generosity, but will only be generous when they have enough saved up. They read that first will be last and the last will be first, yet will try like everyone else to be first. They live like this and wonder why their faith is ultimately unsatisfying.
Peace in life comes when we're living consistently with who we are. We were created as citizens of the Kingdom of God, so when we live lives that are inconsistent with that identity, we'll be dissatisfied. I find that I have much more peace in life the more I live consistently within my Kingdom identity.
Over the course of my life, I've been conditioned to think and act otherwise. I've been taught, explicitly or accidentally that if I want to be happy, I have to look out for myself, money will make me happy, and that it's OK for me to react to people differently depending on how they treat me. Growth is that process of unlearning those things I've been taught by the world and learning to be who I really am. Who God created me to be.
