ISB ~ 1 Corinthians 3 v1

men of the flesh:Immature Christians who possess the Spirit but are enslaved to worldly ways of thinking. The “jealousy and strife” (3:3) exhibited in Corinth was proof that many of them were spiritual infants. Real Christian maturity produces the fruits of love and unity (Gal 5:22-23; Col 3:12-15).
