How do we know God's drawing is effective for salvation?

In John 6:44, Jesus states, 'No man can come to me, except the Father which hath sent me draw him.' This means that the divine drawing is not merely an invitation but an effective action of God that results in salvation. When God draws someone, it is by His sovereign power, and it guarantees that the person will respond positively. This is in line with the confession of historic Reformed theology, which emphasizes that God's grace is irresistible and that all whom He elects will ultimately be saved and come to Christ, fully realizing the promise that they will be raised up on the last day.
