Violence

Matthew 11:12 - From the days of John the Baptist the kingdom of heaven has suffered violence and violent people take it by force.

Yeah. Ok. This is a weird one. How exactly does one do violence to the kingdom of heaven and how would one going about taking it by force? And, since they are still in the days of John the Baptist (technically) how recent is this idea? Is this one line that was added later?

Possibly inflicting violence on its prophets? Such as John the Baptist as well as Jesus himself? Taking it by force - could that be the rulers who collaborated with the Romans while running the temple?

More importantly, what does this phrase mean to me today? If I speak against God (kingdom of Heaven), does God suffer violence or are we talking about harsh words or actions? Hmm

I feel as though I'm missing something!
