The Christian life is a growth. We don’t remain the same as we were in the beginning. If we do, then we are not growing.
We all start out as babies. Babies need to be fed and taken care of. We can’t expect a baby to take care of themselves, let alone take care of anyone else. We can’t reason with a baby or ask them to make important decisions for us.
1 Peter 2:2 tells us that we are to be like newborn babies who desire the spiritual milk.
Like newborn babies, you must crave pure spiritual milk so that you will grow into a full experience of salvation. Cry out for this nourishment, (1 Peter 2:2 NLT)
Babies are cute and adorable. You love watching them play and experiencing things for the first time. Watching them fills us with joy. But even though we might love babies, if we had one and it failed to grow we would know for sure that something was wrong.
And if that child was growing but didn’t want to eat anything but milk, then I am sure we would be concerned that they were not getting enough nutrients to ensure that they were growing properly.
Paul talks about a group of people who, instead of maturing and getting a more mature diet, they remained on milk.
1 Corinthians 3:2 (NLT)
I had to feed you with milk, not with solid food, because you weren’t ready for anything stronger. And you still aren’t ready
But, Paul also presents a contrast to those who failed to grow at all or those who were growing but only wanted milk.
Ephesians 4:13 (NLT)
This will continue until we all come to such unity in our faith and knowledge of God’s Son that we will be mature in the Lord, measuring up to the full and complete standard of Christ.
Paul talks about the end result of growth- being completely like Christ.
1 Corinthians 13:11 NASB
When I was a child, I used to speak like a child, think like a child, reason like a child; when I [d]became a man, I did away with childish things.
