why are you so dumb sometimes?

so says Jesus.

last night, like right after i had written the blog below this one, i did my quiet time and laughed out loud at the Bible for maybe the first time ever and had to do this.
sometimes Jesus' disciples were so dumb.
sometimes we are so dumb.

ok so after Jesus feeds the 4000 (see like.. 2 entries down. another part that made me laugh, thinking we're so faithless and stupid sometimes), they leave and the Pharisees and Sadducees come up to Him and ask for a sign from Heaven. He brings up a saying (which i never knew was from the Bible but i've known it for such a long time), which roughly is: red sky at night, sailor's delight; red sky in the morning, sailors take warning. and tells them how they can make these predictions about the weather and interpret those but they can not interpret a sign from Heaven. He tells them they won't get one because they won't believe it anyways and will keep asking for more.

so then Jesus and the disciples go off somewhere else, and all of a sudden the disciples realize that they forgot to bring bread for them. so Jesus (still talking about what just happened earlier) says "be careful...be on your guard against the yeast of the Pharisees and Sadducees" [matt16:6]. and they think He's mad at them for forgetting to bring along bread.
i'm not even really sure why it makes me laugh. how many parables did Jesus have to use (and then explain out to them) before they could understand that what He said wasn't always exactly what He meant. that there was meaning behind it. they're freaking out because they don't have food and He's trying to teach them about who to follow and what to believe... idk maybe it's just me that finds it funny.
haha so then He starts scolding them for having such little faith in Him and His teachings. like how is it really possible for them to STILL not understand what He's saying. they just got done with these two huge miracles of feeding thousands and thousands of people with 12 loaves of bread and some fish and yet they're still focused on physical needs like the food rather than what He's spiritually trying to communicate to them.

so anyways, after He basically has to spell it out for them again, they understand that it's about not following the teachings of the Pharisees and Sadducees and following Him.

how many times does He have to spell it out for us and prove to us that He completely 100% knows what's going on. when are we going to stop worrying about little things like food and material things and start worrying about furthering His kingdom?
