God is sovereign, but no passages declaring this truth1,2,3 necessitate or even connect it with His saving grace being irresistible. The closest to this is possibly Paul’s statement in Romans3, but properly contextualized4,5,6,7,8,9,10,11,12,13 it’s clear that Paul is not arguing for any kind of “irresistible grace”. If he were, he would be directly contradicting what he believed about himself13 and what he taught the Romans3 and the very clear warning to the Corinthians12.
We see this same reality in statements from Jesus4 where He speaks of the surety of God’s promises. God’s sovereignty (even His love3,8) and man’s reaction to Him are mutually exclusive4,5,6,7,11,13 and demonstrated in statements about the Holy Spirit10. Even the saved (or “elect”) can “refuse” and “reject” God5,6,7,8,13. In fact, Scripture elaborates on the severity and difficulty in returning if this occurs9.
