Thereis a significant difference between "faith" as taught by Jehovah's Witnesses and what non-JW Christians generally experience. Knowing the difference may help you make a decision, one that may help you find a religion that adds to your life, or like Cofty states, discover that a non-religious path fits you better.
Jehovah's Witnesses see faith as a response that believers are totally responsible for. For them it is based on a scholastic approach: studying the Bible and linking texts to come to conclusions that demonstrate a particular logic, one generally supporting Wachtower concepts. The study produces conclusions that are called "evidence" upon which to create or support beliefs. Mental acknowledgment and heartfelt devotion to these conclusions is what is called "faith" among the Witnesses. Any doubtful thoughts must be readily dismissed and are often seen as a sign that one is not a "true believer."
In mainstream Christian theology "faith" is a supernatural virtue. While like the Witnesses it consists of a personal response that includes assent of the mind and the will, according to religious people it has a divine dimension that without makes it totally impossible. Unlike JW doctrines which require belief based on the study and research and complete action of the devotee, the other type allegedly results in belief through an action of God which the devotee does not personally generate.
Scripture and Christian doctrine refers to religious faith as a product or "fruit" of contact with the Holy Spirit. (Galatians 5.22) Unlike Watchtower "faith" which is supposed to be the result of study and contact with the Governing Body, this other "faith" comes from some sort of contact with God. The contact allegedly results in revelation that allows persons to arrive at conclusions or assent to religious "truths" that could not fully believed in by pure human effort. (Compare Galatians 1.11-12 with Matthew 16.15-17) Whereas Witnesses often claim that they believe in their unique doctrines through their own efforts of study, beliefs backed by "evidence" and reason, the other type is said to be a stand-in or personal resolve when there is no evidence or reason to work with, even when there is nothing but reason for doubt.--Hebrews chapter 11.
So for those looking for a church or religion along Christian lines, one's choice is generally made depending on which path may aid in bringing about this response. For them it is about coming into contact with something that is transcendent, generally defies reason, and causes a person to respond with "leaps of faith," courageous steps which generally would not be done by the same individual alone.
This in no way means that a non-theist way is any less courageous. Not all persons take a path that adds to the community of humanity by a religious practice. If you find that nothing speaks to you in the religious world and that you are more taken to adopt convictions based on more humanistic effort, a fulfilling life can also be found according to the testimony of many atheists.
Again, if religion seems to be the path that calls to you, unlearn the Witness way of doing things. Religion is supposed to be the embracing of something greater, that transcends, that recognizes that we can't know everything or expect to be totally right about everything. Belief in this send becomes the result of some spiritual contact, not the manner in which one makes themselves religious.
If you wish to be part of a religion, be sure it is a way that helps you be free to be yourself, not something that takes that freedom away from you or makes you think you can judge others for taking paths exercising similar freedom but holding different convictions.
