How do we know salvation is all from God?

The assurance that salvation is entirely of God comes from a multitude of biblical passages that emphasize His sole role in the process. Romans 8:28-30 articulates God's call of His elect, stating, 'For whom he foreknew, he also did predestinate to be conformed to the image of his Son.' This underscores the belief that every aspect of salvation, from election to glorification, is planned and executed by God. Therefore, belief in this doctrine rests firmly on the relentless witness of Scripture that attributes every facet of salvation to God’s sovereign work, rendering human merit obsolete.
