How do we know that Jesus secures the salvation of His people?

The assurance of salvation for believers rests on the finished work of Christ, who bore the sins of His people and made atonement for them. Scripture emphasizes that Christ's sacrifice was specifically for His elect, those chosen before the foundation of the world. His role as a sower of precious seed reflects His commitment to ensure that none whom He has chosen will be lost, as He intercedes for them even now. Passages like Isaiah 53:5 and John 10:28 confirm that Jesus actively secures salvation by being both the sacrificial Lamb and the Good Shepherd.
