What does the Bible say about effective calling to sinners?

The effective calling to sinners is clearly shown in the ministry of Jesus, where He engages with publicans and sinners, demonstrating His mission to seek and save the lost. As seen in Luke 5:1-2, those who recognized their need for Him approached Jesus, and He received them, affirming that He came for sinners, not the righteous. The narrative illustrates that God's nature is to love those He has chosen for salvation, emphasizing that this calling is powerful—when God calls, no one can resist, unlike the ineffective calls made by mere human effort. The work of Jesus is not superficial; it transforms the heart, leading to genuine repentance and faith.
