How do we know that spiritual discernment is important for Christians?

In the context of 1 Corinthians 2, spiritual discernment is crucial for recognizing the wisdom of God compared to human wisdom. The natural man's inability to perceive spiritual things underscores the importance of discernment for Christians. As believers, we are empowered by the Holy Spirit to gauge the truth of the gospel and live according to Christ's righteousness. Without discernment, we risk being swayed by worldly philosophies that oppose the knowledge of God. Thus, spiritual discernment ensures that our understanding and expressions of faith are aligned with biblical truths.
