How do we know we are called out of darkness?

The assurance that believers are called out of darkness comes from the scripture, particularly 1 Peter 2:9, which states that we are a chosen generation, a royal priesthood, and a holy nation. This new identity reflects God's transformative work through Christ, who has delivered us from the dominion of darkness and brought us into His light. Recognizing this transition is fundamental for Christians, as it sets the basis for living a life that glorifies God and showcases His marvelous deeds.
