Why is trusting in God's promises important for Christians?

For Christians, trusting in God's promises provides a foundation for their faith and assurance of salvation. In the context of sovereignty and grace, believers are called to rely not on personal merit but on God's faithfulness to His word as demonstrated in scripture, particularly in Romans 9:6-9 and the narratives of the Old Testament. The fulfillment of God’s promises reassures believers that God is active and involved in their lives. Moreover, as highlighted in the article, one's assurance ultimately rests not on personal or familial lineage but solely on the Word and promise of God, emphasizing the need for a personal faith that sees one's sin and relies on Christ’s perfect sacrifice.
