Maturing as a Christian means realizing more and more the flesh is a toothless lion that can only intimidate us with it's mighty roar but which has no teeth with which to consume us. I'm 36 years into this and I'm still learning this. But I know much, much more about that than I did when I first started out in my new life. The milk knowledge of the gospel is wonderful. I mean, what adult doesn't like a milk shake now and again, lol. But the intent was not that we live on the milk knowledge of the gospel the rest of our lives, but to mature and begin eating the meat of the word, learning how to live righteous lives through the down payment of the righteousness that God has imputed to us by the Holy Spirit. And what adult doesn't like a good steak now and again!
