What does the Bible say about God's grace in saving Noah?

In Genesis 7:1, God commands Noah to enter the ark, indicating that Noah was chosen to be saved from the impending judgment. This act of grace highlights the sovereign nature of God’s mercy, as it was not due to Noah's works but solely the divine favor bestowed upon him. Romans 9:15 echoes this theme when God states, 'I will have mercy on whom I will have mercy.' Noah's inclusion in the ark serves as a testament to the miraculous nature of God's saving grace, which is not based on human merit but on God's sovereign will.
