How old are you?

I have been wondering why so many christians refuse to grow in Christ? I am not trying to be mean but many will agree with me that so many christians never seem to grow out of childish things. How long have you been saved? Does your age in Christ reflect your response to life? Do the same things that hindered your walk with God years ago still have an affect on your life today? I remember growing up my best friend, John Rochester and myself would play for so long that we would end up getting tired of each other and fighting...I used to get so mad when he would play iwth the toy that I wanted to play with...sound familiar? It happens in church all the time...why can't I do that? Why does he/she get to do things I don't get to do? Why do they get to play with the toy I want? It's time to Grow up in the house of God!! Let's get to it.
