How do we know that God's grace draws sinners to Christ?

The doctrine of irresistible grace asserts that God effectively draws His elect to Himself. As demonstrated in John 6:44, Jesus states that no one can come to Him unless the Father who sent Him draws them. This vital truth illustrates how, amidst the chaos of their sinful lives, the awakened sinner is sovereignly brought to the one true resting place: Christ. Moreover, in 1 Peter 2:25, it is reaffirmed that the sheep who have gone astray will return to the Shepherd, showcasing God's faithful promises to redeem His chosen ones through grace. This drawing is not contingent on human action, but a sovereign act of God.
