The term "Infants in Christ" refers to new believers who are in the early stages of their spiritual journey. This concept is rooted in the metaphorical language used by the Apostle Paul to describe the spiritual maturity of believers. In 1 Corinthians 3:1-2, Paul writes, "Brothers, I could not address you as spiritual, but as worldly—as infants in Christ. I gave you milk, not solid food, for you were not yet ready for it. Indeed, you are still not ready." . Here, Paul likens new believers to infants who require milk, symbolizing the basic teachings of the Christian faith, as they are not yet ready for the deeper, more complex doctrines.

The imagery of spiritual infancy underscores the need for growth and development in the Christian life. Just as physical infants require nurturing and care to grow, spiritual infants need guidance, teaching, and encouragement to mature in their faith. This growth process involves moving from a basic understanding of the gospel to a deeper comprehension and application of biblical truths.

In Hebrews 5:12-14, the author further elaborates on this concept: "Although by this time you ought to be teachers, you need someone to reteach you the basic principles of God’s word. You need milk, not solid food! For everyone who lives on milk is still an infant, inexperienced in the message of righteousness. But solid food is for the mature, who by constant use have trained their senses to distinguish good from evil." . This passage emphasizes the expectation that believers should progress from spiritual infancy to maturity, becoming capable of discerning and teaching the truths of the faith.

The nurturing of infants in Christ is a communal responsibility within the body of believers. The church plays a vital role in providing spiritual nourishment through teaching, fellowship, and discipleship. Ephesians 4:11-15 highlights the purpose of church leadership in equipping the saints for this growth: "And it was He who gave some to be apostles, some to be prophets, some to be evangelists, and some to be pastors and teachers, to equip the saints for works of ministry and to build up the body of Christ, until we all reach unity in the faith and in the knowledge of the Son of God, as we mature to the full measure of the stature of Christ." .

The journey from spiritual infancy to maturity is marked by an increasing understanding of God's Word, a deepening relationship with Christ, and a growing ability to live out one's faith in everyday life. This process is empowered by the Holy Spirit, who indwells believers and guides them into all truth (John 16:13). As infants in Christ grow, they are called to "put on the new self, created to be like God in true righteousness and holiness" (Ephesians 4:24), reflecting the transformative power of the gospel in their lives.

In summary, the concept of "Infants in Christ" serves as a reminder of the importance of spiritual growth and maturity in the Christian life. It highlights the need for foundational teaching, communal support, and the work of the Holy Spirit in nurturing believers from infancy to maturity in their faith.
