Jesus said, "Do not give dogs what is sacred; do not throw your pearls to pigs.”
Whoa! On a scale of rude, that's right up there near the top.
Jesus was talking about people who are chronically antagonistic toward His message, His existence and His Father, our Father, Creator God.
Jesus was talking to those who want to pass along His message of salvation to these people.
He was saying, don’t waste your time on those who believe they are good without God. They may as well be in hell already. And since the gates of hell are locked from the inside, forget about em. If those to whom He was speaking had searched His face for any sign that He was joking, they'd have seen nothing. Jesus was a serious as He could be.
Jesus, our role model regularly hid the things of God from those who “were wise in their own eyes.”
To people who are humble, to people who are spiritual seekers, Jesus gives more than they ever ask for.
On the other hand, the self-righteous are deliberately blinded from finding the Truth, they're kept from finding Him. The dogs and pigs of whom Jesus speaks are those who absolutely reject their own or anyone else's hunger and thirst for righteousness.
Gentle Jesus. No wonder people want to kill him.
