How do we know the faith of the elect is true?

The Apostle Paul highlights the nature of the faith of the elect in Ephesians 2:8-9, stating that salvation comes by grace through faith, which is not of ourselves; it is the gift of God. This emphasizes that true faith is a result of God's sovereign work in the hearts of the elect. Believers are called to examine themselves to ensure they have this true, God-given faith and not a mere form of belief rooted in human tradition or effort. The assurance of this faith comes through the acknowledgment of its divine origin and the personal relationship with Christ as its author.
