Why did Noah build the ark?

Noah's decision to build the ark was driven by faith, responding to God's revelation about the coming flood. Hebrews 11:7 states that, 'by faith, Noah...prepared an ark to the saving of his house.' This act demonstrated his obedience and trust in God amid widespread disbelief and mockery. Noah's faith in the unseen led to a tangible action that not only preserved his family but also condemned the world around him for their unbelief, showcasing the dramatic implications of faith in the life of a believer.
