Definition and Concept:
Eternal Remembrance refers to the enduring memory and recognition of individuals or events in the divine perspective, as understood within the Christian faith. It encompasses the belief that God, in His omniscience, retains a perpetual awareness of His creation, particularly those who are faithful to Him. This concept is rooted in the assurance that God does not forget His promises or His people, and it is often associated with the hope of eternal life and the final judgment.

Biblical Foundations:

1. God's Unfailing Memory:
The Bible frequently emphasizes God's perfect memory and His commitment to remember His covenant with His people. In Isaiah 49:15-16 , God reassures Israel of His unfailing remembrance: "Can a woman forget her nursing child, or lack compassion for the son of her womb? Even if she could forget, I will not forget you! Behold, I have inscribed you on the palms of My hands; your walls are ever before Me."

2. Remembrance in Worship and Prayer:
The act of remembrance is integral to worship and prayer, where believers recall God's past deeds and promises. Psalm 77:11 states, "I will remember the works of the LORD; yes, I will remember Your wonders of old." This practice serves to strengthen faith and trust in God's continued faithfulness.

3. The Book of Remembrance:
Malachi 3:16 introduces the concept of a "book of remembrance" written before God for those who fear Him and honor His name: "At that time those who feared the LORD spoke with one another, and the LORD listened and heard them. So a book of remembrance was written before Him regarding those who feared the LORD and honored His name." This metaphorical book signifies God's acknowledgment and reward for the righteous.

4. Eternal Life and Judgment:
Eternal remembrance is closely linked to the Christian hope of eternal life and the final judgment. Revelation 20:12 describes the scene of judgment where the dead are judged according to their deeds, as recorded in the books: "And I saw the dead, great and small, standing before the throne. And there were open books, and one of them was the book of life. And the dead were judged according to their deeds, as recorded in the books."

5. The Memorial of the Righteous:
The righteous are assured of eternal remembrance in God's sight. Psalm 112:6 declares, "Surely he will never be shaken; the righteous man will be remembered forever." This promise provides comfort and motivation for believers to live lives that honor God.

Theological Implications:

1. Assurance of God's Faithfulness:
Eternal remembrance underscores the reliability of God's promises. Believers can trust that God will not forget His covenant or His people, providing a foundation for hope and perseverance.

2. Moral and Ethical Encouragement:
The concept encourages believers to live righteously, knowing that their deeds are remembered by God and will be rewarded. It serves as a deterrent against sin and a motivation for holiness.

3. Hope in Suffering and Persecution:
For those enduring trials, the assurance of eternal remembrance offers comfort. It affirms that their struggles are not forgotten and that God will ultimately vindicate and reward them.

4. Eschatological Perspective:
Eternal remembrance is integral to the Christian eschatological outlook, where the final judgment and the hope of eternal life are central themes. It reinforces the belief in a future where justice is fully realized, and God's people are eternally acknowledged.

Conclusion:
Eternal Remembrance is a profound biblical theme that assures believers of God's unfailing memory and faithfulness. It provides comfort, motivation, and hope, encouraging a life of righteousness in anticipation of God's eternal acknowledgment and reward.
