A baby doesn’t hop, skip, and jump into adulthood. Growing up and becoming a spiritual adult is a process, not a single event. God is blessed when He sees His children making the transition from babyhood into adulthood in a spiritual sense. God wants us to move from the spiritual nursery to the spiritual battlefield. He wants us to leave the realm of milk, bibs and diapers and He wants us to enter the realm of meat, battles and devotion.
In a very real sense, this maturing process will go on for the rest of our natural lives. Our lives are filled with ups and downs, trails, and tribulations, with the struggles of the flesh and the spirit. God has made maturity possible for every believer, but what we do with our time determines the rate of our progress in arriving at the destination of maturity. When you get discouraged remember, when God starts a project, he completes it! As with the Philippians, God will help us grow in grace until he has completed His work in our lives {Philippians 1:6}.
