Best not to question. Just have faith.

Watchtower May 1 1958 p. 261 Is Your Religion the Right One?
“It is important, then, that you "keep testing whether you are in the faith," as Paul declared. Keep checking to see whether the things you believe are in keeping with God's Word. But the question is, Are you willing to put your religion through such a test? There is nothing to fear, because if you have the right religion you can only be reassured by the examination. And if what you believe is not in keeping with the Bible, then you should welcome the truth, because it leads to light and life. - Isa. 8:20, Dy; 2 Cor. 13:5.”
