It needs to grow up!

I was thinking the other day of Joseph and his brothers.... Joseph we all know was destined for greatness and almost ruined it by not keeping his mouth closed, but that's a story for another day... What made me think about him was his brothers. There was a significant age gap between him and his older brothers. Joseph grew up being not only the youngest, but the favorite son. I can only imagine what they were thinking. To have been a fly on the wall the day they decided to sell him into slavery.... 

The reason why I was thinking about them was because of what happened later in the story when they had their encounter. His brothers did not know it was him. Many believe that it was because they thought he was dead. The revelation I received was that they never let him grow up. To them,except Benjamin, Joseph never stopped being the bratty little brother. He never stopped being the brother that said "I had a dream that there were 11 bushels of wheat in a circle bowing down to me."  They did not allow for him to grow up, to change.
I came to this revelation a few days ago because I was thinking that there were things in my life that grew up with me, but then there are other things that either didn't because they weren't supposed to or I didn't allow them to. I think that is a mistake many of us make. When we don't let things grow. We get caught and our ideas on something become stale.

But why is that? Do we sit down one day and just decide not to let things change?

Or is it just easier for things to stay how they are and where they are?
I found myself thinking this as I approached my 28th birthday.... I realized that there are a few things in my life that I either missed out on because I never let them grow up or that I got into because I was going on old information....

What about you? Are there things in your life you need to let grow up?
