Seek and you will find, knock and the door will be opened, ask and it will be given to you. (Matt. 7:7)
Of course the above assumes one criteria that most do not meet: genuineness (or another way to say it "genuine desire to know what truth is").
See you can be a "Pilate" and when life is getting difficult and you are confronted with something that challenges your lifestyle (in his case it was Jesus), you call out "WHAT IS TRUTH?", not because you want to know but because your fear causes you to deflect the spotlight on your conscious and you hope getting entangled in verbal arguments will lead us away from that which you falsely seek: Truth.
Or you can be a "Jacob" and when something or Someone comes to challenge you, you spit on your hands, throw off your baggy shirt, hunch down and get ready for the greatest wrestling match of your life. And here's the thing: you don't let go until you understand.
That's how you find the right religion
