What does it mean to call God the God of Jacob?

Referring to God as the God of Jacob highlights His transformative grace towards those who seem undeserving. Jacob, who was known as the 'supplanter,' symbolizes the grace given to sinners—those who, regardless of their inherent flaws, are chosen and loved by God. Scripture illustrates that Jacob's elect status is not based on works but solely on God's mercy. Therefore, Christians call upon the God of Jacob, recognizing Him as the one who helps and saves they who do not merit such grace, thus fostering true humility and reliance on Him.
