Conversations with Mrs. L - Can We Change? (Part 2)

Continuing from Can We Change? (Part 1) , Apple and I looked at each other, surprised that Mrs. L didn't directly answer but she asked me instead. Apple's question was "Can we change?" (please see the previous two posts for context). I turned back to Mrs. L and answered her, "Yes, we change." 
Mrs. L laughed again and she said, "That's right. That's right. We change." It's a metabolic change.

For those who are seeking the Lord, we get disappointed because we keep failing at being better Christians. On one hand, yes, it's true our fallen nature doesn't really change. Those who love to talk would still love to talk, those who love to be silent would still love to be silent. I'll give you an illustration. A toddler would throw herself on the floor and cry and scream to get someone's attention whenever she's having a bad day, hungry, unhappy, etc. Well, an adult could be having a bad day, hungry, unhappy, etc. but she would no longer throw herself on the floor and cry and scream to get someone's attention, would she? Humanly, people change because they become more mature in life.

Spiritually, it's the same way. Yes, we change but the changing within our being is not by imitation nor by outward efforts, it's by a metabolic change that causes us to grow to be more mature in the spiritual life (best illustration is to look at how our human body grows). 

We need to spiritually eat and drink to grow, to get the nutrients we need. Our true food and true drink is Christ Himself in His Word and as the Spirit. He is the Bread of life (John 6:35) and the water of life (John 4:14).
