Today’s topic hits close to home for many people. Toxic people aren’t just “difficult personalities.” According to the Bible, their behavior often stems from deep spiritual dysfunction. In this installment of our “How Stuff Works” series, we examine what really drives toxic people and how we can respond biblically and wisely.

We’re looking at the tragic life of King Saul, Israel’s first king. At first, Saul appeared to be a promising leader—anointed by God, popular with the people, and empowered to lead. But his story quickly derailed due to unchecked insecurity, spiritual rebellion, and destructive behaviors that poisoned his relationships and led to his downfall.

Through Saul’s life, we uncover four key truths about how toxic people work. This study will help you understand toxic patterns, identify red flags, and—most importantly—learn how to respond like David did: with grace, boundaries, and wisdom.

Scripture Reference: 1 Samuel 18:6-9 (NLT)

When David rose to fame after defeating Goliath, Saul’s jealousy ignited. Rather than celebrating David’s success, Saul saw him as a threat.

This response reveals a deep insecurity—a fear of being replaced, overshadowed, or exposed. Toxic people often present as confident or successful, but beneath the surface is a fragile identity rooted in comparison and fear.

Spiritual Insight:

True security comes from knowing you are made in the image of God. Without that, people seek worth through achievements, control, or praise. Saul had no mentor to guide him toward that deeper security—and it cost him everything.

Scripture Reference: 1 Samuel 19:9-10 (NLT), Romans 1:28, 1 Timothy 1:19-20

After rejecting God's authority, Saul became vulnerable to spiritual torment. The Bible says “a tormenting spirit from the LORD” came upon him—a judgment, not cruelty. God gave Saul over to his rebellion, just as Romans 1 warns.

Toxic behavior can be a form of spiritual warfare. Satan works through envy, rage, deceit, and division—the very qualities that defined Saul’s descent. He went from throwing spears to throwing accusations and lies.

Common toxic traits tied to this:

• Manipulative
• Controlling
• Judgmental
• Blaming others

Contrast this with the fruit of the Spirit (Galatians 5:22-23): love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.
