How to reconcile God telling Jeremiah to preach to people that won't listen while also saying not to cast your pearls before swine

God tells Jeremiah to preach to people that will not listen: > **Jeremiah 7:2,27 NIV** - Stand at the gate of the Lord’s house and there proclaim this message...[*long message*]...When you tell them all this, they will not listen to you; when you call to them, they will not answer. Later on in biblical history, Jesus, whom Christians believe to be God, tells his crowd to not waste words on people that won't listen: > **Matthew 7:6 NIV** - Do not give dogs what is sacred; do not throw your pearls to pigs. If you do, they may trample them under their feet, and turn and tear you to pieces. What's an overview of Christian responses to how these two things can coexist without contradiction?
