Signs have purpose and meaning attached to them. There will be times when your life may be in danger, and God is trying to protect you. The only way that you will be completely protected is to take heed to the warning, and not ignore the signs that are being presented to you. A sign has no meaning to a person that does not pay attention, or does not take a warning serious. Warning always comes before destruction.
Genesis 19:14, 17, 22 says “So Lot went out and spoke to his sons-in-law. He said, “Hurry and leave this city! The Lord will soon destroy it!” But they thought he was joking. So after the two men brought Lot and his family out of the city, one of the men said, “Now run to save your life! Don’t look back at the city, and don’t stop anywhere in the valley. Run until you are in the mountains. If you stop, you will be destroyed with the city!” But run there quickly. I cannot destroy Sodom until you are safely in that town.”
Be blessed, be encouraged, and have a great day.
