How do we know that God will preserve His elect?

The assurance of God's preservation of His elect is grounded in His immutable character and the promises found in Scripture. For instance, Romans 8:34 declares that Christ’s intercession secures the justification and eternal life of believers. If Christ has died for a person, that individual cannot perish, as that would frustrate God’s purpose and the efficacy of Christ's sacrifice. This demonstrates that God's plans are not contingent upon human actions but are eternally secured by His will, ensuring that all whom He has chosen will arrive safely to salvation.
