How does one put away childish things in their spiritual life?

According to Paul in 1 Corinthians 13:11, putting away childish things means abandoning immature ways of thinking and behaving, which are characteristic of those governed by the world. This transition happens through the grace of God when one becomes a new creation in Christ. As believers grow in their understanding of God's character and love, they develop a deeper relationship with Him that prompts them to forsake prior ways of reasoning and acting that do not align with His truth. Engaging with God’s word and cultivating love for Him naturally leads believers to a maturity that dismisses petty grievances and self-centeredness.
