How does Jacob's vow reflect the nature of salvation?

Jacob's vow in Genesis 28:20-22 signifies his understanding of God's promises and grace. When he says, 'If God will be with me,' he acknowledges that his salvation and perseverance depend entirely on God's faithfulness, not his efforts. This reflects the essential Reformed tenet that God initiates and secures our salvation. Jacob’s commitment to dedicate a tenth to God illustrates gratitude and acknowledgment of God's provision, resonating with the believer's call to respond to God's grace through faith and works inspired by that grace.
