How do we know that we have been called by God?

The evidence of God's calling in our lives is seen through a genuine change of heart, where previously we were in darkness but now seek after the light of the gospel. This calling is a divine act where God illuminates our hearts, leading us to a desire for spiritual realities and a relationship with Christ. Ephesians 2:1-5 beautifully illustrates this, stating that we were dead in our sins until God made us alive together with Christ. This transformation reflects the faithful work of God in our lives, confirming our calling.
