Why does God refer to Himself as the God of Jacob?

In Psalm 46:7, God refers to Himself as the 'God of Jacob' to remind His people of His faithfulness and love towards those He has chosen. Jacob symbolizes the undeserving, yet favored people of God, highlighting that God's love is based on His sovereign grace rather than their merits. This name serves as a reassurance to believers, emphasizing that despite their failings and struggles, God remains committed to them. The reference to Jacob reinforces the truth that God's nature is to extend mercy and uphold a covenantal relationship with His people, fostering hope and security for generations.
