In case you question that, the central theme of Jesus' teaching has to do with the Kingdom. The late Professor David Flusser, an Orthodox Jew who taught at the Hebrew University in Jerusalem, wrote, "Jesus regarded the Kingdom of Heaven as taking shape around him and together with him. Later on, Christianity was influenced by this idea, but in a somewhat distorted manner, and identified the idea of Kingdom of Heaven with the community itself, the Christian church , or with redemption after death. Jesus stood at the center of a movement which was to bring about, step by step, the realization of the Kingdom of Heaven on earth, and it was in accordance with this idea that he explained the miracles, the signs and the healings he brought about for the people. Miracles, in Jesus' view, were not isolated phenomena, but were evidence that the devil had already fallen and they were beholding the realization of the Kingdom of Heaven on earth."
Who wrote that? A Jew – not a Christian – who understood from the words of Jesus what Jesus meant by Kingdom. It was the Kingdom of Heaven, the demonstration of God's power in action. And when Jesus began to preach, what was it that he began to preach? The Kingdom of Heaven is … what? At hand? No. At hand means it's close by. In Hebrew, it means it's here!
Jesus begins to preach saying, Turn around in your thinking! Rearrange your thinking. Repent! Do an about face, because the Kingdom is here! I have come to usher it in, and I'm going to gather around myself those who are ruled by God, and together we're going to move out in an anointing of power that people will be able to see the demonstration of God's rule in this world, and their lives will be changed by it!
So when Jesus says repent, for the Kingdom of God is at hand, he means, change your thinking; change your direction, because it's here. That for which you have been waiting is here.
In verse 19, as he goes along the shore of the Sea of Galilee and he sees the fishermen, Simon and his brother Andrew, he says to them, "Follow me." What does that mean? Walk after me, or come after me? Actually, this term is a Hebrew idiom. It was used by many of the rabbis. It means, "walk behind me," or as we translate it into English, follow me. But it is actually the call of the rabbi to the student to come and to learn from him. So in saying, follow me, to Simon and Andrew, he's inviting them to come and to learn from him and to be a part of his movement, to set forth, not just principles of the Kingdom but to … what?
Here is the validation of everything that I've just told you. Look at verse 23: "And Jesus went about all Galilee teaching in their synagogues and preaching the Gospel of the Kingdom, and healing all manner of sickness and all manner of disease among the people. This shows that the anointing of Jesus on those of the Kingdom was not just to teach and to preach, but that their teaching and preaching would make the people whole. It would change their lives. Something was going to happen for the now! Not just for pie in the sky by and by. And that’s where we've missed it. We are other-world oriented. Christianity is basically a religion of death. We can't wait to die! We can't wait to get out of here to get our rewards. The mansions over in Gloryland. I've often said I'm not interested in a mansion in Gloryland; I need someplace to live now. I'm not interested in pie in the sky by and by; I'm hungry now.
That’s the difference between biblical faith and churchanity. Churchanity is other-worldly, where biblical faith is now. It looks at the person now and sees him where he is now, and it extends the hand of the Kingdom to meet that person where he is and ministers to him according to his need in order that he might be made whole.
