How do we know the atonement is for the chosen?

The doctrine of limited atonement affirms that Christ’s sacrifice was specifically intended for the elect, as articulated in Matthew 26:28, where Jesus said His blood was shed for many. This must be understood in the context of His redemptive work — it was designed to secure salvation for those whom the Father had given Him. As John 10:11 describes, Jesus is the Good Shepherd who lays down His life for His sheep, highlighting that His sacrifice is efficacious and intentional, aiming to effectively save and redeem those chosen before the foundation of the world.
