Apostle John goes out of his way all throughout his gospel to tell us how people responded to Jesus. He doesn’t only tell us what Jesus says and does, but also what peoples reactions were to the things that He says and does. All throughout his ministry, Jesus said outrageous things that everyone who knew of Christ, met Christ or heard Him teach; had an opinion about him. In John 7, you see multiple different responses to Jesus. Some hated him, some thought he was a criminal, some thought he was brilliant, others though he was a miracle worker, and a select few believed he was God in the flesh. But, how does one know? How do we know the truth about who Jesus really was behind all of the opinions and claims that others has about him?
In John 7:17 Jesus tells us that there is a way to know. "If anyones will is to do Gods will, he will know whether the teaching is from God or whether I am speaking on my own authority." The way to know whether or not Jesus is truly who he says he is (God in the flesh, sent from heaven, to pay the penalty for sin.) is to have a willingness to do the will of God. In other words, in order to know that Jesus is the truth, it requires you seeking after him as the truth. Not just with your mind, but also with your actions. Jesus is saying that when you seek me with your mind, and your actions, you will find me. If you only seek Jesus with your mind, you'll become at best an Intellectual. If you only seek Jesus with your actions, you'll become at best a Religious Moralist. But when you seek Him with your mind and actions, your eyes will be open to how truly glorious He actually is.
