I'm not sure what you are asking, perhaps you don't know either. You ask this question as though each Christian is sitting before Jesus doing a bible study and He specifically gave each of them a answer to a question they put before Him. I can speak for myself, and perhaps in prayer, or before a big decision or in the quiet of bible study, a question is quietly answered within my soul...a voice...that says go to college, or my role in life is to help people...or been warned not to go down a road that I later learned there was a bad accident and lives were lost...or in a very low point of my life, when I thought to kill myself, a felt a embrace like a mother does to a child that go me through the roughest night of my life and I am still here today. Others, non-believers would pass off many things, whisperings, someone coming to us in a time of need, another who helps us to answer a question we had be tossing around in our minds, a donation of money, a basket of food, as coincidences, or chance...but incidences where so sound and sure, we know it was God or Jesus's answers, messages or directions on choices we should choose. Outside of that, the bible has a lot of answers to questions we pose daily...you can choose ot open you heart and seek to find the answers or choose to daily ask God to prove He exists by asking Him to do stunts for your eyes to observe.
