Why is understanding the nature of Satan important for Christians?

Recognizing that Satan is a deceiver and accuser is essential for Christians, as it equips believers to understand the spiritual warfare they face. The sermon references 2 Corinthians 11, highlighting how Satan disguises himself as an angel of light, leading many away from the simplicity of the Gospel. By understanding the tactics of Satan and the implications of our own sinful nature, we can resist him by steadfastly holding onto our faith in Christ, who alone provides the truth we need to combat deceit. This knowledge fortifies believers against doubt, helping them to maintain their confidence in God's promises and their identity in Christ.
