Brothers and sisters, I could not address you as people who live by the Spirit but as people who are still worldly—mere infants in Christ. I gave you milk, not solid food, for you were not yet ready for it. Indeed, you are still not ready. You are still worldly. For since there is jealousy and quarreling among you, are you not worldly? Are you not acting like mere humans? For when one says, “I follow Paul,” and another, “I follow Apollos,” are you not mere human beings? (1 Corinthians 3:1-4)
There are two types of Christians: The people who live by the Sprit and the people who live by their flesh (Who are worldly) In here Paul describes the people who are still worldly as “mere infants in Christ”
I had to ask my self: Am I still an infant in Christ? Am I asking for milk only, because I’m not ready to handle the solid food? There was another verse that re-iterated this point:
Anyone who lives on milk, being still an infant, is not acquainted with the teaching about righteousness. But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil. (Hebrews 5:13-14)
Here is a characteristic of someone who’s still an infant in Christ and lacks maturity. They are jealousy and quarreling amongst Christians which results in lack of unity and division. (They’ll follow different religious leaders and idolize them instead of focusing on Christ and his leadership) Also they are not aquatinted with the teaching about righteousness. Because the righteousness comes from Christ and Christ alone.
However when we take a look at someone who are mature and living by the spirit, they truly have a correct understanding of righteousness through Christ, and they can discern what is good and what’s not.
We need to stop drinking milk and move on to digesting solid food.
