Hebrews 2 states, Therefore we must pay much closer attention to what we have heard, lest we drift away from it. For since the message declared by angels proved to be reliable, and every transgression or disobedience received a just retribution, how shall we escape if we neglect such a great salvation? It was attested to us by those who heard, while God also bore witness by signs and wonders and various miracles and by gifts of the Holy Spirit distributed according to his will. Whenever you encounter a sign, rather through dreams, vision, or road signs pay attention. What does it mean? Remember when you took your driving test you couldn't receive your license unless you passed. That required following the instructions and listening. That's the same thing with any other sign. What did you learn from it?
