We all tend to believe in what we hope to be true and disbelieve what we hope to be false. When Dr. Scott Hahn and many other Protestant ministers first found that the Catholic Church might be the original church Jesus had established upon Peter, they all wished that it wasn't true and hoped hard that some learned Protestants would prove that they were right. When none were able to, they all converted and came home. A current example is given by those who support Trump and those who are against him. The former believe in everything that Trump does, while the latter bash whatever he does. When it comes to accepting Christ, those who hope that he is not the truth for whatever reason just avoid confronting him. So the Lord does not stand a chance if we do not start out being neutral. To be objective and openminded is absolutely necessary in seeking the truth, for otherwise you cut off any possible benefits you might receive, treating yourself unfairly from the very beginning.
