How can know the heart? It's a common misconception that following your heart leads to happiness. However, this is a dangerous lie from the devil, masking the true risks of trusting your heart. In reality, your heart can lead you down the wrong path, causing regret and anger. The state of your heart affects every aspect of your life, and it's crucial to be mindful of its influence. The Bible warns that "The heart is deceitful above all things and desperately wicked," and relying on it can lead you away from your faith in God. Instead, use your intelligence and faith to build a fulfilling relationship with God.
