You don't need to believe and have faith in a God or an immortal soul to believe and faith in Love. Although I personally believe in a God and an immortal soul (that belief and faith having nothing what so ever to do with a religion of any kind mind you), but even if I didn't believe and faith in God or an immortal soul I would still believe and faith in Love.

The first reason I chose to believe and have faith in Love regardless of a God or an immortal soul, is it makes me feel good! It makes me happy, it fills me with the need to create. I tried living in fear it made me only feel mad, it made only feel sad and the only thing it allowed me to create was new ways to try to destroy myself. It froze my mind and limited my choices to fight or flight. I never did want to fight and grew tired of running a long time ago.

The second reason I chose to believe and have faith in Love regardless of a God or an immortal soul is our history. We have been living in and ruled by fear almost since the dawn of civilization, almost since our first question, why? and it hasn't worked out so well for us thus far. If everything was going just perfect and we had created a society with a sustainable future, I would say, cool, lets keep on fearing, but no one is saying that. Each day we are living in fear, we are one more day closer to this, our reality no longer being here. So from a purely logical perspective, if what we have been doing for many thousands of years has not been working, why not try something different and for me that something different is Love.

The third and most important reason I chose to believe and have faith in Love regardless of a God or an immortal soul, is that now that I know Love unconditionally, I can be no other, as it is now and always was I believe (always meaning in this lifetime, lest I give you the idea I am talking about immortality) what I am.

I believe and have faith Love is what we all are. I believe Love is what makes nature function. I believe the reason that we are such a dysfunctional species is because we have chosen not to BE the Love we are and that choice has thrown us out of synch with rest of nature, which requires that there be mutually beneficial relationships, (lets call those loving relationships) in order for species to thrive and to evolve. We existing mostly without Love are neither thriving or evolving.

For all these reason I chose to belief and have faith in Love regardless of God or an immortal soul, but as I said I do believe in God and an immortal soul (just not religion) and it is for all these reasons that I hope we all chose to believe and faith Love regardless...
