Book of Hebrews - Chapter 5 - Verse 14

As explained in this verse, strong spiritual growth and understanding come with maturity and experience in walking with God. Just as infants start with milk before moving on to solid food, new believers may begin with simpler spiritual truths before delving into deeper, more complex teachings. Those who are "of full age" in their faith have honed their spiritual senses through practice and application, allowing them to discern between good and evil. This discernment is crucial for navigating the complexities of life and making sound moral decisions. By actively engaging with Scripture and applying its teachings in their daily lives, believers can strengthen their ability to discern the difference between right and wrong, ultimately growing in spiritual maturity and wisdom.
