The people were amazed at his teaching, because he taught them as one who had authority, not as the teachers of the law...What is this? A new teaching—and with authority! He even gives orders to impure spirits and they obey him. [Mark 1. 22 and 27]
It wasn't just that his teachings were sound and bible (Old Testament) based. First and foremost, his teachings were new. Yes, it was solidly Old-Testament based, but it was in tune to the minute developments in the Kingdom of God. Freshly Kingdomly.
Second, it had power. It wasn't just inspiring or motivational, as most preaching styles today are---amusing and entertaining but powerless. Modern, seminary-inspired speaking styles intrigue the mind but not the spirit.
With Genuine Authority
And it wasn't power in the sense that he shouted a lot. That's how most church people today see "powerful preaching"---loud and noisy. Well, a pleasantly loud voice sometimes does help. But the power in Jesus' teaching was genuine signs and wonders.
The devil possessing the man in the synagogue came out "violently" and "with a shriek" at Jesus' short and simple command. All he said was practically, "Sshh! Shut up! Out!" That was it. It was genuine.
Unlike today, most pastors have difficulty getting rid of one tiny demon. They have to shout loudly, issue dozens of commands, do lots of rituals, need back up from the worship team and prayer warriors, and yet produce little effect, if any.
Worse, others just dismiss the possibility of demon possession and demons showing themselves in weird forms, saying they aren't real. Truth is, they really don't know what to do because all they know is their human theology.
Yes, Jesus started his preaching ministry inside a traditional synagogue, but his ways were far from what you regularly and traditionally saw in synagogues. For starters, he did the miracle there on a Sabbath, which was a definite no-no because it was against all sound theology at the time.
Second, he wasn't a member of the Judaism religion and so had no right to use the synagogue. His ways were clearly non-Judaist.
I'm sure the law teachers and Pharisees also derived their teachings from the Old Testament as Jesus did. And yet, when Jesus taught it, everything came out "new." No one's ever heard about it until then. It was not "another teaching," but it was "a new teaching." It was a new development straight from God's very own Kingdom at that very moment. It was the latest and hottest headline from heaven's newspaper.
It was the Gospel. It was the power of God in human form. Never had anything like it ever seen on planet earth.
The religious teachers only got shallow meanings, barely scratching even the shadow of things to come, because they weren't sons. All they extracted from the Word were weak materials good only for human theology and doctrines.
But Jesus, as the Son, got the mind of the Father and the creative thinking of the Holy Spirit. And with Jesus Himself 100 percent living in true sons and daughters of God today, they should get the same results.
Now if we are children, then we are heirs--heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in his glory. [Romans 8.17]
So, why did Jesus teach differently, making sure he was worlds apart from the teaching styles of the highly educated law teachers? Answer---because Jesus wanted to make sure that only sons and daughters were able to catch his Kingdom messages.
Here's the secret---Jesus taught in unorthodox fashion so that the wise in this world would not get anything from it. They are doomed to prefer only what derives from their human traditions, human theology and denominational doctrines. They are doomed to appreciate only what amuses and entertains.
But God chose the foolish things of the world to shame the wise; God chose the weak things of the world to shame the strong. God chose the lowly things of this world and the despised things—and the things that are not—to nullify the things that are, so that no one may boast before him. [1 Corinthians 1.27-29]
And after my skin has been destroyed, yet in my flesh I will see God; I myself will see him with my own eyes—I, and not another. How my heart yearns within me! [Job 19,26-17]
