What's the Meaning of the Initial Statement and the Follow Up?

If jesus is saying, blessed are you simon barjona, you're an insignificant pebble. I will give you the keys to the kingdom of heaven. Then we should interpret the middle statement in its context and say, that's all so a blessing. So when i realize that, i had to conclude the other arguments i had were weak compared to this. This structure is so obvious, you can see it even in english, and it points to peter being the rock when you read it in context. Why don't we go to the next slide? There we go.
