Paul calls some believers 'infants' and 'people of the flesh.' What does that really mean, and how does it differ from being truly spiritual?
Paul isn't saying these Corinthian believers were unsaved. Instead, he's drawing a sharp distinction between two ways of living within the Christian life:
Living by the Spirit
This is the life God intends for us after conversion. It's characterized by dependence on the Holy Spirit, yielding to God's will, and bearing the fruit of righteousness. It's maturity.
Living by the Flesh
This refers to living according to one's unredeemed sinful nature, even after becoming a Christian. It's driven by selfish desires, divisions, and worldly wisdom rather than God's wisdom. It's immaturity, even if they possess spiritual gifts.
Paul’s word choice here, 'people of the flesh,' is a strong indicator that their current behavior is regressing to a state that should be left behind after salvation. It’s not about having the Spirit, but how you are allowing the Spirit (or not) to guide your life.
