Basically, to grow, is like when a child is first a newborn. They start out on milk and eventually begin eating solid food.
Now let's get this going! I will be posting more on maturity than on baby Christians.
Ephesians 4:15 NIV
 Instead, speaking the truth in love, we will grow to become in every respect the mature body of him who is the head, that is, Christ.
Jesus be with you all. Amen.
