In the final episode of "Defenses Against Deception," Duane teaches that maturity is the sixth defense in guarding against deception, especially in the Christian faith. One of the primary reasons many people depart from the faith is immaturity - being carnally minded and lacking spiritual discernment.

How can professing Christians embrace immorality, vote for leaders who oppose biblical values, and support unbiblical ideologies that celebrate sinful behaviors? The root cause of this departure often lies in a lack of genuine salvation and spiritual rebirth. Some attend church and try to live a moral life, mistakenly believing that this alone secures their salvation. True Christianity, however, involves a spiritual transformation through being born again, with God's Spirit dwelling within and empowering a new life in Christ.

Even among those genuinely born again, many fail to transition from being new converts to becoming mature disciples of Christ. They remain spiritual infants, unable to properly understand and apply the deep truths of God's Word. The path to maturity requires humility – acknowledging one's limitations, remaining teachable, and submitting to God's ways rather than pridefully clinging to one's own understanding. As the Apostle Paul affirmed, when he became a man, he put away childish things, recognizing and discarding immature thought patterns and behaviors.

Ultimately, maturity is not the absence of all immaturity but the ability to discern and willingly lay aside immature mindsets and actions. It is a lifelong process of growth, enabled by God's grace, as believers press on to know Christ more intimately and become conformed to His image.
