Sincerity

God has been teaching me a lot about sincerity in the last few months. I try not to say anything I don't mean or do anything that is later going to contradict something I said. For example (an this isn't against anyone in particular), if I saw I want to take you out to lunch I mean it. I'm not going to change my mind and take the offer back, that would just be rude and inconsiderate. So for the record: no one needs to ask me if I'm sure :) my offer is given freely and not with a feeling that I have to do so.
There are those though that you can just tell right off from the start that they are not being sincere. I think this may be one of my pet peeves. Have you ever had a person who claims they are your friend, but more in reality they are nothing more than an acquaintance because the friendship they offer isn't sincere and you can't get to fully know them? Or they offer something or do something for you because they feel obligated to do so. I think sincerity relates to being real and honest with one another and not holding things back.
I think God wants us to be so real in our interactions with one another that sincerity just naturally occurs with out even having to contemplate about doing so. If you don't think I'm being sincere, let me know so that I can be real with you.
Just a thought that God has been challenging me with lately. Maybe it can speak to you as well.
