He lived by it.
Wrong.
Matthew 5:44 But I say to you: Love your enemies. Do good to those who hate you. And pray for those who persecute and slander you.
And he didn't do that. Death threats in Luke 13:
"I tell you, no! But unless you repent, you too will all perish."
And in Mark:
"Whoever believes and is baptized will be saved, but whoever does not believe will be condemned."
And in John:
"Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him."
And in Matthew:
"But I say to you that everyone who is angry with his brother will be liable to judgment; whoever insults his brother will be liable to the council; and whoever says, ‘You fool!’ will be liable to the hell of fire."
He explicitly denied forgiveness in Matthew:
"And so I tell you, every kind of sin and slander can be forgiven, but blasphemy against the Spirit will not be forgiven."
Telling people to fear him in Matthew 10:
"And do not fear those who kill the body but cannot kill the soul. Rather fear him who can destroy both soul and body in hell."
Condoning slavery and beating slaves in Luke:
"And that servant who knew his master's will but did not get ready or act according to his will, will receive a severe beating. But the one who did not know, and did what deserved a beating, will receive a light beating."
Matthew 5:45 In this way, you shall be sons of your Father, who is in heaven. He causes his sun to rise upon the good and the bad, and he causes it to rain upon the just and the unjust.
How does one live by this bullshit? "The sun comes up. Good and bad people get rained on." So?
Matthew 5:46 For if you love those who love you, what reward will you have? Do not even tax collectors behave this way?
Matthew 10:
"“Do not think that I have come to bring peace to the earth. I have not come to bring peace, but a sword. For I have come to set a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law. And a person's enemies will be those of his own household."
And you're conveniently ignoring that all of Jesus's "love" was founded on "OBEY ME OR SUFFER".
