In 1 Corinthians 3:1-7, the Apostle Paul confronts the Corinthian church about their spiritual immaturity, emphasizing the need for deeper growth in faith. He categorizes people into three types: the natural man, who is alienated from God; the spiritual man, led by the Spirit; and the carnal man, a believer still dominated by the flesh. Carnality, characterized by envy, strife, and divisions, prevents spiritual growth and leads to a conflicted existence. Paul urges believers to repent genuinely, moving from basic teachings ('milk') to deeper, more substantial teachings ('solid food'). This spiritual journey involves gathering knowledge, reasoning with it, and applying it in daily life. By using our God-given gifts and trusting Him for growth, we can overcome carnality and mature in our faith, contributing to God's kingdom.
