Why is believing God's promises important for Christians?

For Christians, believing God's promises is foundational to their faith and relationship with Him. As illustrated by Abraham, who believed God’s promise despite impossible circumstances, this belief is credited as righteousness. Abraham’s faith exemplifies the believer's trust in God’s faithfulness and ability to fulfill His promises. This trust not only ensures justification but also fosters a deeper relationship with God, allowing believers to rest in the assurance of salvation that stems from God’s grace rather than their works. Hence, believing entails not just intellectual assent but an active trust in God's nature and purpose.
