“But I know that you do not have love for God (literally ‘the love of God' where the genitive is objective) within yourselves. I am come in my Father's name and you do not receive me, if another comes in his own name him you will receive.”
But by their refusal to hear Him they were revealing that they neither loved God, nor had His love in their hearts. For if they had truly loved God they would have recognised Him for what He was and would have received Him, for He came in the Father's name, seeking only glory for Him. Their failure to come demonstrates therefore that their love for God is simply feigned. Rather they love themselves and their own carefully worked out religion, and they love those who seek their own glory.
‘If another comes in his own name, him you will receive.' And the supreme irony is that when men come in their own name claiming great things for themselves they will receive them. And indeed the day would soon come when they would follow different persons, and follow them to disaster, both before the final destruction of Jerusalem, and after (see Acts 5:36-37). Then they would follow different glory-seeking Messianic leaders to destruction. Then they would rise against the Romans and see Jerusalem destroyed (66-70 AD). Then they would see the ‘star of David' in Bar Kochba (132-135 AD), resulting in the further destruction of Jerusalem. That would be because they did not seek God's interests, but their own, interests which they would convince themselves were God's. But if they had really known God's ways they would not follow such leaders.
This point was particularly poignant. Jesus sought no glory, desired to be given no authority, united Himself with no group, sought to establish no army, and encouraged men to fully follow the Law, as expanded by Him (Matthew 5), and attend the synagogue. He pointed men only towards God. And their antagonism towards Him came simply because He preached truth according to the Scriptures, the Scriptures that they claimed to trust.
