Why is it essential to understand spiritual adultery?

It is essential for Christians to recognize spiritual adultery, as it represents a departure from the truth of the gospel, leading to severe consequences. The Bible illustrates that seeking righteousness outside of Christ, like engaging with false gospels, can result in eternal separation from God. Recognizing the symptoms of spiritual adultery—such as self-righteousness or mixing law and grace—encourages believers to cling to the gospel as their only source of hope and salvation, ultimately safeguarding their faith.
