How do we know that heavenly rewards are true?

The certainty of heavenly rewards is grounded in the teachings of Jesus and the Apostle Paul. For instance, in Matthew 5:12, Jesus promises great rewards in heaven for those who are persecuted for His sake, emphasizing the expectation of future recompense. Moreover, Paul reiterates this theme in I Corinthians 3, noting that each will receive a reward according to their labor, thereby affirming that such rewards are not based on merit but on divine grace in the believer's life. The contextual interpretation of these passages reveals that God Himself is the ultimate source of the eternal rewards that await believers, assuring their reliability. Additionally, Romans 8:28-30 further illustrates how all things work together for those called according to His purpose, offering comfort that God's promises are both secure and certain.
