How do we know that God chooses certain people for salvation?

The doctrine of election is clearly articulated in John 17, where Jesus acknowledges that He prays only for those whom the Father has given Him. This notion of being chosen reflects God's eternal plan and purpose in salvation, which is rooted in His love and mercy. Throughout scripture, passages affirm that before the foundation of the world, God predestined a people for Himself (Ephesians 1:4-5). This understanding not only emphasizes God's sovereignty but also assures believers of their identity as part of His elect, giving hope and security in their relationship with Him. The assurance that their salvation is not contingent upon works but secured through divine grace enhances their worship and faithfulness.
