It certainly does match up and it's called harmonizing scripture with scripture.
Yes, Jesus NEVER knew them because they were NEVER saved.
Children of the devil practice lawlessness, not children of God (1 John 3:7-10) which matches up with bad tree/bad fruit; fruitless branches.
UNBELIEVERS.
BAD FRUIT because false prophets are bad trees.
It's either GOOD or BAD. Nothing is mentioned about the good tree going bad at some point. It was bad all along.
Because they are BAD trees, which represents unbelievers.
Because they were UNBELIEVERS. Jesus NEVER knew them.
Good description of Judas Iscariot who was never saved, but was an unbelieving, unclean devil who betrayed Jesus (John 6:64-71; 13:10-11). *See how this all fits together?
Exactly! Scripture must harmonize with scripture. I say that all the time.
