Final answer:
Paul uses the Covenant of Promise to emphasize faith without works, while James emphasizes the importance of works in addition to faith.
Step-by-step explanation:
In Genesis 15, both Paul and James refer to the Covenant of Promise made between God and Abraham. However, they differ in their emphasis and interpretation of its significance.
Paul uses the Covenant of Promise to describe the promise of salvation. He emphasizes the importance of faith without works, stating that salvation is attained through faith in God's promise rather than through works of the law.
On the other hand, James uses the Covenant of Promise to describe the promise of blessing. He emphasizes the importance of works in addition to faith, stating that faith without works is dead.
Therefore, the correct answer is A. Paul uses it to emphasize the importance of faith without works, while James uses it to emphasize the importance of works.
