How do we know that Christ will not let His bride perish?

The assurance that Christ will not allow His bride to perish stems from His complete work of redemption on the cross. As the designated bridegroom, He has satisfied the demands of God's justice by bearing the sins of His people. This is affirmed in Romans 8:1 where it states, 'There is therefore now no condemnation for those who are in Christ Jesus.' The security of believers rests not on their works but on Christ's sacrificial love, which guarantees their preservation and eternal glory. Because of this, His bride can rest in the promise that no one can snatch them from His hand, ensuring their final salvation.
