Romans 7:15

For I do not understand my own actions (I am baffled and bewildered by them). I do not practice what I want to do, but I am doing the very thing I hate (and yielding to my human nature, my worldliness-my sinful capacity).

We will make mistakes and not always behave like we should as Christians! Jesus is not surprised when we fall short of His example. We must get back up when we fall short and ask for forgiveness and change. As Christians, we realize that Jesus died for the imperfect and will help us in our weaknesses.
