How do we know that God remembers His own?

The assurance that God remembers His own is a comforting truth found in Malachi 3:16, where it states that a book of remembrance was written before the Lord. This does not imply that God forgets, but rather serves as a metaphor comforting us that He meticulously keeps track of His people. Such remembrance reflects His eternal faithfulness and unyielding support through life's trials. In 2 Timothy 2:19, we are reminded that 'the Lord knows them that are his,' signifying His intimate relationship with each believer. He will never forget or overlook those He has redeemed.
