All religions have seeds of truth. Sooner or later, but everyone understands that God is one for all religions, teachings, faiths, philosophies, etc., and it doesn't matter what we call him or her, or what concept we build around it (God is one for all forms of life, even for aliens at the other end of the Universe, etc.) To put it simply, God is Love in different manifestations. When we do something right, we act according to our conscience, a particle of God awakens in us - our immortal spiritual foundation. This material world was created for the development of our soul (you can call it differently, the essence does not change). To save yourself means to merge with your soul through conscience and right actions on the path of life. We come into a series of reincarnations in this material world as individuals (without the acquired skills and experience of Love), and we leave here as developed personalities, ready to go higher and higher into those worlds where there is no time and space, where there is only Love.
