How do we know that the promise of a crown is true?

The assurance of a crown for believers is encapsulated in the promise of God, which is confirmed throughout the New Testament. Particularly in 2 Timothy 4:8, Paul declares, 'Henceforth there is laid up for me a crown of righteousness.' It is crucial to understand that this crown is not something earned by our works but is a gift of grace bestowed on those who are in Christ. Our hope rests on the character of God and the finished work of Jesus at the cross, which guarantees that nothing can sever us from His love. Therefore, the foundation of this promise is the unchanging nature of God, who always fulfills His word.
