Why is man's enmity against God important to understand?

Man's enmity against God is a crucial concept in Reformed theology as it reveals the total depravity of humanity. According to Psalm 2 and supported by Acts 4, this enmity is universal, affecting all people due to the fall of Adam (Romans 5:12). This reality underscores the necessity for a Savior to reconcile humanity with God. It emphasizes that apart from God's intervention and the workings of the Holy Spirit, people are in rebellion against their Creator, making the message of grace even more profound and essential.
