John 8:42 - Matthew Poole's English Annotations on the Holy Bible

This agreeth with what we have 1 John 5:1, Every one that loveth him that begat, loveth him also that is begotten of him. But here our Saviour rather seemeth to speak of his proceeding forth and coming from God, as sent into the world to fulfil the will of God as to the redemption of man, than of his proceeding from his Father by eternal generation. It is true, that he who loves the father will also love the child, so far forth as he resembles his father, and acts like unto him; and it is as true, that he who loveth him that sends a messenger will also love the messenger, executing the commission of him that sent him.
