How do we know that Jesus died specifically for the elect?

The assertion that Jesus died specifically for the elect is rooted in the biblical teaching found in passages such as Mark 14:24, where Jesus refers to His blood as that of the New Testament, shed for many. This 'many' is understood as the elect, in accordance with the doctrine of limited atonement within Reformed theology. It affirms that Christ's atonement accomplishes what it intends: the salvation of those given to Him by the Father. This is further supported by passages like John 10:14-15, where Jesus identifies Himself as the Good Shepherd who lays down His life for His sheep, emphasizing the particularity of His sacrifice.
