If you met a boy who is funny, handsome, intelligent and sweet, (everything you've ever wanted in a boyfriend), how long would you have to know him to marry him? Wouldn't you want to take a lot of time for you both to get to know each other before you committed to marriage? You wouldn't expect to create and maintain a relationship in just a matter of a few weeks or months. How much more this is true with God and Jesus.
If you believe in a creator and savior, it will take a lot of soul searching and study to determine what is right for you. Certainly a loving God would afford you the time to do so.
