“Aren’t people supposed to lead people to Jesus?”
Yes, but not just people.
“Hasn’t the law been done away with?”
Yes and no. If you want to wear a wool and linen blend, or eat a hot dog, or work on a Friday night, have at it. If you want to worship idols, or take the Lord’s name in vain, or steal, or murder someone, you’re headed for trouble.
I got that wrong. Jesus came to fulfill the law.
