11 The Jewish leaders tried to find him at the festival and kept asking if anyone had seen him. 12 There was a lot of grumbling about him among the crowds. Some argued, "He's a good man," but others said, "He's nothing but a fraud who deceives the people." 13 But no one had the courage to speak favorably about him in public, for they were afraid of getting in trouble with the Jewish leaders.
14 Then, midway through the festival, Jesus went up to the Temple and began to teach. 15 The people were surprised when they heard him. "How does he know so much when he hasn't been trained?" they asked. 16 So Jesus told them, "My message is not my own; it comes from God who sent me. 17 Anyone who wants to do the will of God will know whether my teaching is from God or is merely my own.

Commentary on John 7:1-13
(Read John 7:1-13)
The brethren or kinsmen of Jesus were disgusted, when they found there was no prospect of worldly advantages from him. Ungodly men sometimes undertake to counsel those employed in the work of God; but they only advise what appears likely to promote present advantages. The people differed about his doctrine and miracles, while those who favoured him, dared not openly to avow their sentiments. Those who count the preachers of the gospel to be deceivers, speak out, while many who favour them, fear to get reproach by avowing regard for them.
Commentary on John 7:14-24
(Read John 7:14-24)
Every faithful minister may humbly adopt Christ's words. His doctrine is not his own finding out, but is from God's word, through the teaching of his Spirit. And amidst the disputes which disturb the world, if any man, of any nation, seeks to do the will of God, he shall know whether the doctrine is of God, or whether men speak of themselves. Only those who hate the truth shall be given up to errors which will be fatal. Surely it was as agreeable to the design of the sabbath to restore health to the afflicted, as to administer an outward rite. Jesus told them to decide on his conduct according to the spiritual import of the Divine law. We must not judge concerning any by their outward appearance, but by their worth, and by the gifts and graces of God's Spirit in them.
