The wicked people of Noah’s day procrastinate their repentance until it is too late. The Flood comes, and water covers the whole earth. All other life that breathes is destroyed.
Genesis 7:23
23 And every living substance was destroyed which was upon the face of the ground, both man, and cattle, and the creeping things, and the fowl of the heaven; and they were destroyed from the earth: and Noah only remained alive, and they that were with him in the ark.
President Henry B. Eyring said:
“The failure to take prophetic counsel lessens our power to take inspired counsel in the future. The best time to have decided to help Noah build the ark was the first time he asked. Each time he asked after that, each failure to respond would have lessened sensitivity to the Spirit. And so each time his request would have seemed more foolish, until the rain came. And then it was too late.
“Every time in my life when I have chosen to delay following inspired counsel or decided that I was an exception, I came to know that I had put myself in harm’s way. Every time that I have listened to the counsel of prophets, felt it confirmed in prayer, and then followed it, I have found that I moved toward safety. Along the path, I have found that the way had been prepared for me and the rough places made smooth. God led me to safety along a path which was prepared with loving care, sometimes prepared long before.”
