How do we know God has not forgotten His people?

In Isaiah 49:15-16, God reassures His people that even if a mother may forget her child, He will never forget them. He emphasizes His intimate knowledge of them, stating, 'I have graven thee upon the palms of my hands.' This metaphor illustrates the permanence of His care and commitment. For Christians, it signifies that regardless of circumstances in life that may sway their feelings, God's faithfulness and love remain unwavering. His grace and mercy toward His people assure them of His presence, even when it seems He is silent or distant.
