Growing Up Is Hard To Do

It is funny to me that getting older and growing up are not necessarily the same thing. I think the older that we get the more stuck in our ways we get as well. I suppose there is nothing wrong with this, but with that being said the more closed minded we become the less child-like we are.

Matthew 18:3 "And said, Truly I say to you, unless you repent and become like little children, you can never enter the kingdom of heaven."

I strive to be child-like (trusting, loving, forgiving, non-judgemental), but its a hard thing to accomplish sometimes, especially when you feel so passionate about something. Some of these child-like qualities I have an easier time with than others. I have a fairly hard time with forgiveness. They say "forgive and forget", but unless you really forget what someone has done to you and never bring it up again, then you really aren't forgiving anyone. I guess trust and forgiveness go hand in hand because when you forgive, you are trusting someone not to hurt you the way they did before.
I think I do pretty good on not being judgemental, but I do know that I struggle with that from time to time. I think that there are many ways to do things and I don't tend to have the attitude that "my way is the best and that makes me better than everyone else." But, on the other hand, when someone is judgemental towards me, I don't all the time just "turn the other cheek". I get very bothered when people pass judgement on me partly because I am very defensive over the things I do in my life because usually I put a lot of thought and research into those things.
Just because we get older, doesn't mean we grow up. To me growing up means having a knowledge of the world and being passionate about your beliefs, but at the same time, acting in an adult manner with love and kindness in your heart. When you harbor hatred for someone or something no matter for what reason, it will eat away at you and prevent you from growing.
