How do we know that Christ's work on the cross was for his people?

The certainty that Christ's work on the cross was for his people is grounded in Scripture. In passages such as John 10:15, Christ states, 'I lay down my life for the sheep', indicating that his atonement is specifically for those given to him by the Father. This particularity of Christ's redemptive mission is echoed throughout the New Testament, affirming that his death and resurrection provided salvation exclusively for the elect, those whom God has chosen. Furthermore, Romans 5:8 states, 'But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.' This illustrates that the act of salvation is both intentional and personal. Such assurance invites believers to rest in the full efficacy of Christ's work on their behalf.
