In the seventh episode of "Nurturing Spiritual Growth," Duane emphasizes the importance of Christian maturity and urges believers to grow into the likeness of Christ in every aspect of their lives. Spiritual maturity is not only about obtaining salvation and securing a place in heaven but also about living out heavenly principles here on earth. This means demonstrating behaviors that align with being citizens of heaven rather than reflecting our old, sinful natures.

In 1 Corinthians 13, the Apostle Paul speaks about putting away childish things when becoming a man. This metaphor describes the journey from spiritual childhood to adulthood, highlighting that maturity involves more than aging or having spiritual gifts. Possessing spiritual gifts does not necessarily equate to maturity, as gifts can be misused if character and love do not accompany them.

The true measure of spiritual maturity is characterized by love and the correct use of God's gifts. It's possible for believers to operate in gifts of the Spirit and still be immature if they lack the foundational love of God, which should direct all actions. Immaturity can lead to misusing spiritual gifts, potentially causing harm to oneself and others. This misuse demonstrates a lack of spiritual development, which should ideally blend the operation of gifts with a mature character formed by God's love.

1 Corinthians 13, famously known as the "love chapter," underscores that spiritual gifts must operate out of love to be genuinely effective and beneficial. This love is not just an abstract feeling but a concrete force that should guide all interactions and the exercise of spiritual gifts.

Duane also addresses the concept of spiritual food in terms of "milk" and "meat." He explains that spiritual milk represents the basic, foundational teachings of Christianity essential for new believers, while spiritual meat involves doing God's will. Just as physical children grow from milk to solid food, spiritual believers must progress from elementary teachings to more profound truths.
