God isn’t keeping us from sin because it’s “fun and great” but he just doesn’t want us to do it.

Sin is death, God knows it will destroy us, and he wants what is best for us.

Jesus was very good at this. He scolded the very wicked harshly and those who would not follow he left with their own thoughts.

Matthew 10:14 KJV And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.
