'Warned' in the Bible
These serve as a copy and shadow of the heavenly things, as Moses was warned when he was about to complete the tabernacle. For God said, Be careful that you make everything according to the pattern that was shown to you on the mountain.
By faith Noah, after he was warned about what was not yet seen and motivated by godly fear, built an ark to deliver his family. By faith he condemned the world and became an heir of the righteousness that comes by faith.
Make sure that you do not reject the One who speaks. For if they did not escape when they rejected Him who warned them on earth, even less will we if we turn away from Him who warns us from heaven.
