To Come With Broken Hearts

In GW on pages 237 and 238 it talks about how we're to come with a suitable disposition and it uses a lot of referencing to how we're supposed to be able to connect with how Christ did all that he did for us and we're to feel such broken heartedness in knowing that.
How are we even supposed to begin to connect with that in the way it's making it seem here? It's so hard to really truly connect with on such a level. We weren't there to witness it happening and most of us haven't had a circumstance in our lives that would help us connect with that so deeply.
What's a way that could actually help us to connect our hearts with that brokenness?
