The concept of reward is a recurring theme throughout the Bible, reflecting the justice and faithfulness of God in His dealings with humanity. The certainty of reward is rooted in the character of God, who is both just and gracious, and it is a principle that applies to both temporal and eternal blessings.

Old Testament Foundations

In the Old Testament, the certainty of reward is often linked to obedience to God's commandments. The Mosaic Law, given to the Israelites, contains numerous promises of blessings for obedience and warnings of curses for disobedience. Deuteronomy 28 outlines these blessings and curses in detail, emphasizing the direct correlation between faithfulness to God and the receipt of His rewards. "And all these blessings will come upon you and overtake you, if you will obey the voice of the LORD your God" (Deuteronomy 28:2).

The wisdom literature, particularly the book of Proverbs, frequently addresses the theme of reward. Proverbs 11:18 states, "The wicked man earns an empty wage, but he who sows righteousness reaps a true reward" . This proverbial wisdom underscores the moral order established by God, where righteousness leads to reward.

New Testament Teachings

In the New Testament, the certainty of reward is expanded to include eternal dimensions. Jesus Christ, in His teachings, often spoke of rewards in the context of the Kingdom of Heaven. In the Sermon on the Mount, He assures His followers of heavenly rewards for their faithfulness and righteousness: "Rejoice and be glad, because great is your reward in heaven; for in the same way they persecuted the prophets before you" (Matthew 5:12).

The Apostle Paul also emphasizes the certainty of reward, particularly in relation to the believer's service and perseverance. In 1 Corinthians 3:8, Paul writes, "The one who plants and the one who waters have one purpose, and each will be rewarded according to his own labor" . This passage highlights the individual nature of reward based on one's work for the Kingdom.

Eternal Perspective

The certainty of reward is not limited to earthly life but extends into eternity. The book of Revelation provides a vivid picture of the ultimate reward for the faithful. Revelation 22:12 records the words of Jesus: "Behold, I am coming soon, and My reward is with Me, to give to each one according to what he has done" . This promise assures believers of the future fulfillment of God's justice and the eternal rewards awaiting them.

Faith and Reward

The relationship between faith and reward is a central theme in the epistle to the Hebrews. Hebrews 11, often referred to as the "Faith Chapter," recounts the accounts of Old Testament figures who lived by faith and received God's commendation. Hebrews 11:6 declares, "And without faith it is impossible to please God, because anyone who approaches Him must believe that He exists and that He rewards those who earnestly seek Him" . This verse encapsulates the principle that faith is integral to receiving God's rewards.

Conclusion

The certainty of reward is a foundational biblical principle that reflects God's justice, faithfulness, and grace. It serves as both an encouragement and a motivation for believers to live lives of obedience, faith, and service, with the assurance that God will fulfill His promises both in this life and in the life to come.
