Why is the story of Noah important for Christians?

The story of Noah, as presented in Genesis, is significant because it shows the seriousness of God's judgment on sin and the grace He extends to those He saves. Noah represents Christ; just as he preached righteousness and built the ark for salvation, Christ offers Himself as the refuge for believers. This narrative exemplifies the concept of being 'in Christ,' where believers find safety from judgment, much like Noah and his family found salvation in the ark. It is a vivid depiction of God's sovereign grace and the necessity of faith.
