How do we know we will inherit eternal life?

The assurance of eternal life for believers rests in the truth that our inheritance is secured in Christ. Scripture reveals that through the gospel, we are endowed with this incorruptible inheritance, as noted in Colossians 3:24, which assures us that we serve the Lord Christ. This inheritance is not based on our works but rather on Christ's complete and perfect redemption given for us. Thus, those who have been regenerated by the Holy Spirit and placed their faith in Jesus have the unshakeable promise of eternal life, reserved for them in heaven.
