How do we know the covenant with Noah applies to Christians?

The covenant established with Noah is not just about God's promise to him; it serves as a type that points to the higher covenant made with Jesus Christ. Just as God remembered Noah and his family during the flood, He has made an everlasting covenant with Christ, which believers are now part of through their faith in Him. This covenant signifies that all believers, who are considered the seed of Christ, are included in God's redemptive plan. It shows how God’s covenant dealings throughout history, including promises made to Noah, connect to the New Covenant established in Christ.
