When I was growing up, my dad had a saying he often used, especially when he thought I was making questionable choices: “Garbage in, garbage out.” I knew what he meant, but I liked to believe I was the exception—that I could take in whatever I wanted, mentally, emotionally, or physically, without it truly impacting me. I figured I was immune, untouchable. Maybe I just didn’t care.
But the reality is, it does matter. What we take in—through our minds, hearts, and daily habits—eventually shapes who we are. The things we allow into our lives influence our thoughts, our words, and, in the end, our actions.
Scripture Readings
• Luke 6:45 (NIV) – “A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of.”
• Proverbs 4:23 (NIV) – “Above all else, guard your heart, for everything you do flows from it.”
• 1 Corinthians 15:33 (NIV) – “Do not be misled: ‘Bad company corrupts good character.’”
Reflection
Jesus reminds us in Luke 6:45 that our words and actions are simply the overflow of what’s in our hearts. What we feed our minds will eventually become the reality of our lives. If we consistently take in negativity, unhealthy influences, or lies, then those things will shape our thoughts and behavior.
Proverbs 4:23 warns us to guard our hearts because everything we do flows from them. If we don’t take this seriously, we allow toxic influences to settle in, affecting our attitudes, choices, and relationships.
Paul echoes this truth in 1 Corinthians 15:33—our surroundings matter. The people we spend time with, the media we consume, and the messages we allow into our minds all play a role in shaping our character. If we surround ourselves with negativity or ungodliness, we shouldn’t be surprised when our faith, integrity, and joy suffer.
The good news? The opposite is also true. When we fill our hearts and minds with truth, wisdom, and righteousness, we’ll see the fruit of it in our lives.
Application
• Self-Examination: What am I consuming daily—through conversations, entertainment, or social media? Is it leading me toward God or pulling me away?
• Prayer and Scripture Reflection: Ask God to help you guard your heart and be intentional about filling your mind with His truth. Spend time in His Word daily.
• Accountability: Surround yourself with people who encourage spiritual growth. Identify influences that need to change.
• Action Step: Choose one area of input to evaluate this week—music, TV, social media, friendships—and make an intentional shift toward what is godly and uplifting.
Closing Prayer
Father, help me to be mindful of what I allow into my heart and mind. Give me discernment to recognize what is drawing me closer to You and what is pulling me away. Strengthen me to make wise choices, to guard my heart, and to surround myself with godly influences. Let my words and actions be a reflection of Your truth and goodness. In Jesus’ name, Amen.
