Some things you can’t un-see or un-hear. Protect your heart and your mind. Junk in means junk out (Matthew 15:18).
This isn’t something we can do on our own, we have to rely on God’s strength and grace (John 15:5).
Lean on Him and guard your heart:
“Keep and guard your heart with all vigilance and above all that you guard, for out of it flow the springs of life.” Proverbs 4:23 Amplified Bible.
