There's different meanings to these words, though. For example, I have many doubts about my future, because everything is uncertain at this point, but with the help of my friends, who I have grown to trust, I have faith that I'll be alright.I don't think it's spiritual in nature. Faith and doubt are also not exclusively connected to spirituality. Trusting someone is based on a foundation of familiarity, and knowledge. I've known one of my best friends for a little over three years, and I would trust that guy with my life, property, and family. That didn't happen overnight, though. It took at least a year for that level of trust and closeness to develop.
Maybe it's spiritual in the way that it's a developed bond between people. It really depends on how we're defining spirituality.
Faith and doubt are spiritual issues. I've had both in my life. Early on, I had many doubts. Faith has meant confidence to me. There certain spiritual things I have confidence in.
Trust is another story. Some people are trustworthy from the very beginning, and they never waver. Trust otherwise, like you say, takes time.
In the religious sense, I have no faith, because I don't trust the words of men who claim to speak for their gods. I was so filled with doubt upon really seeing how miserable the world can truly be, that I could no longer believe in a benevolent, omnipresent force in this world. That doubt led to a very liberating apostasy. The occult phase was fun, though.
