How do we know that the calling of salvation is real?

To ascertain the reality of the calling of salvation, believers often reflect on their personal response to God's voice. Just as Samuel responded to God's call in 1 Samuel 3 by saying, 'Here am I,' true believers know that when God calls them, it resonates deeply within their hearts. This inner conviction is facilitated by the Holy Spirit, who reveals Christ to them. Furthermore, the effects of this calling manifest through a transformation in the believer's life, producing fruits of faith, repentance, and obedience. The assurance of this calling aligns with the biblical truth that God does not leave His sheep lost; He actively seeks and calls them to Himself (Luke 19:10).
