What does spiritual fornication mean in the context of faith?

In the context of faith, spiritual fornication is the act of engaging with ideas or practices that compromise the exclusive sufficiency of Christ. It signifies a turning away from the grace of God and seeking acceptance through worldly means or religious practices, as illustrated by Esau in Hebrews 12:16-17. Just as Esau despised his birthright for immediate gratification, believers can likewise neglect their spiritual inheritance by trading it for temporary desires. This warning emphasizes the importance of steadfastness in the faith and recognizing the value of our calling in Christ, which is paramount in maintaining a true and faithful relationship with God.
