How do we know that grace was given to us before we even existed?

The affirmation that grace was bestowed upon believers before their existence is found in Ephesians 1:4-5, where it is declared that 'He chose us in Him before the foundation of the world, that we should be holy and without blame before Him in love.' This notion is central to the doctrine of sovereign grace, which posits that God's saving grace is not contingent on human activity or decision but is an expression of His eternal purpose. This concept reinforces the assurance of salvation for those who believe, as it underscores that they are part of God's plan from the very beginning and that their salvation is rooted in God's sovereign will rather than their own actions.
