How do we know that all Christians have the same reward in heaven?

The equality of God's love for His people assures us that there are no degrees among believers. Romans 8:29 affirms that all who are in Christ are predestined to be conformed to His image. This signifies that every believer, irrespective of their earthly struggles, is equally justified and cherished by God. Thus, the same redemptive price—the blood of Christ—has been paid for all, ensuring that the promises and blessings of grace are universally applicable. The inheritance awaiting us in heaven is singular and shared, affirming the doctrine that every believer will rejoice in the same eternal glory.
